Abstract
Background:
Present-day chemists are more interested in developing and using green
chemistry protocol for various organic transformations, which employ natural feedstock extracts,
and solvent-free, and greener catalysts; they are well known for their non-hazardous nature and
have replaced many organic and inorganic based catalysts. In literature, the reported homogenous
catalytic approaches have been employed for various bioactive heterocycle syntheses, which follow
the green chemistry principle established for various organic transformations catalyzed by
WERSA, BFE, WEPPA, WEMFSA, WEMPA, and Eichhorniacrassipes. Among them, 2-aryl benzimidazole
derivatives have emerged as prominent molecules with a wide variety of applications in
biological and material science.
Methods:
The agro-waste sourced from the banana peel is utilized for the preparation of BPAE catalyst,
which is employed for the synthesis of 2-aryl benzimidazole derivatives under ultrasound
waves at room temperature.
Results:
Here, 2-Aryl benzimidazoles synthesized through the reaction of a substituted o-phenylene
diamine with substituted benzoyl chloride catalyzed by BPAE under ultrasound waves at
room temperature are described. Furthermore, catalyst BPAE is characterized by flame emission
spectrometry, SEM-EDX, and XRD techniques.
Conclusion:
The present work established an eco-friendly, sustainable and novel approach for the
synthesis of 2-aryl benzimidazoles using natural feedstock BPAE. The major merits of BPAE include
its use as an agro-waste-derived catalyst. It is also highly abundant, inexpensive, yields faster
reactions, has a simple workup, and does not require the use of column chromatography.

Abstract
BACKGROUND A wide variety of biological activities are exhibited by N, O and S containing heterocycles and recently, many reports appeared for the synthesis of these heterocycles. The synthesis of heterocycles with the help of metal and non-metal catalyst has become a highly rewarding and important method in organic synthesis. This review article concentrated on the synthesis of S-heterocylces in the presence of metal and non-metal catalyst. The synthesis of five-membered S-heterocycles is described here. OBJECTIVE There is a need for the development of rapid, efficient and versatile strategy for the synthesis of heterocyclic rings. Metal, non-metal and organocatalysis involving methods have gained prominence because traditional conditions have disadvantages such as long reaction times, harsh conditions and limited substrate scope. CONCLUSION The metal-, non-metal-, and organocatalyst assisted organic synthesis is a highly dynamic research field. For ßthe chemoselective and efficient synthesis of heterocyclic molecules, this protocol has emerged as a powerful route. Various methodologies in the past few years have been pointed out to pursue more sustainable, efficient and environmentally benign procedures and products. Among these processes, the development of new protocols (catalysis), which avoided the use of toxic reagents, are the focus of intense research.

Abstract
:The reactions involving the formation of C-O bond using metal as a catalyst have emerged to be one of the most influential reactions for the synthesis of heterocycles in modern organic chemistry. Catalysis by metals offers diverse opportunities to invent new organic reactions with a promising range of selectivities such as chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. The methodologies used earlier for synthesis were less approachable to the organic chemist because of their high cost, highly specified instrumentation and inconvenient methods. For both stereoselective and regioselective formation of five-membered O-containing heterocycles, cyclic reactions that are metal and non-metal-catalyzed have known to be very efficient. The present review article covers the applications of metal and non-metal as a catalyst for the synthesis of five-membered O-containing heterocycles.

Abstract
Microwave technology has emerged as a great tool for the efficient synthesis of organic compounds and it provides opportunities for chemists to achieve chemical transformations that tend to be challenging using classical approaches. Additionally, N-heterocycles are well-known for their medicinal/biological significance, along with their applications as excellent building blocks in chemical synthesis. The dominance of N-heterocycles in drug molecules and other pharmacological agents makes them attractive scaffolds, which encourages chemists to develop a wide range of strategies towards the greener synthesis and functionalization of these heterocycles. In this regard, we have collated and discussed literature relating to the microwave-assisted synthesis and the modification of non-(benzo)fused single-nitrogen-containing N-heterocycles from the past decade. The role of the microwave technique and its benefits over the conventional approach have also been emphasized in terms of overall reaction efficiency, reaction time, yield, reduced side-product generation, neat and clean reactions, chemo-/regio-/enantio-selectivity, and the use of mild reagents/reaction conditions to achieve the objectives of green and sustainable chemistry.

Abstract
The field of heterocyclic chemistry has been revolutionized using transition
metal catalysts in recent years. Various research groups have focused on the development
of general protocols to achieve better functional group compatibilities and greater levels of
molecular complexity under mild reaction conditions, using easily available starting substrates.
The methodologies used earlier for their synthesis were less approachable to organic
chemists because of their high cost, highly specified instrumentation and inconvenient
methods. For both stereoselective and regioselective synthesis of five-membered nitrogen-
containing heterocycles, cyclic reactions that are Ru-catalyzed have known to be
very efficient. These methods have many advantages as compared to alternative pathways
involved in the synthesis of heterocyclic compounds. In this review article, we concentrated
on the synthesis of nitrogen-containing five-membered heterocycles in the presence of a ruthenium catalyst.
This review mostly covers the literature published during the period from 1977-2019.

Abstract
Due to special properties of ILs (Ionic Liquids) like their wide liquid range, good solvating ability, negligible vapour pressure, non-inflammability, environment friendly medium, high thermal stability, easy recycling and rate promoters etc. they are used in organic synthesis. The investigation for the replacement of organic solvents in organic synthesis is a growing area of interest due to increasing environmental issues. Therefore, ionic liquids have attracted the attention of chemists and act as a catalyst and reaction medium in organic reaction with high activity. There is no doubt that ionic liquids have become a major subject of study for modern chemistry. In comparison to traditional processes the use of ionic liquids resulted in improved, complimentary or alternative selectivities in organic synthesis. The present manuscript reported the synthesis of multiple nitrogen containing five-membered heterocyclic compounds using ionic liquids. This review covered interesting discoveries in the past few years.

Abstract
Ultrasonic irradiation is employed to accelerate organic reactions. Under sonication reduced time, good selectivity, excellent yield, and milder conditions were observed for many organic reactions. Ultrasonic reactions are increasingly used as green, clean, and environment-friendly methods in organic synthesis in terms of energy conservation and waste minimization. The use of ultrasound irradiation is increasing in coming years. The use of ultrasound irradiation in the synthesis of five-membered N-heterocycles is depicted in the present review article.

Therefore, ionic liquids have attracted the attention of chemists and act as a catalyst and reaction medium in organic reaction with high activity. There is no doubt that ionic liquids have become a major subject of study for modern chemistry. More publications in the field have been observed each year, although there is some evidence that this is beginning to plateau at approximately 3500 papers each year. They have been the subject of several major reviews and books, dealing with different applications and aspects of their behavior. Highly efficient methods are explored for the preparation of six-membered two nitrogen-containing heterocycles with the application of IL as a catalyst and reaction medium from 1893 to 2018.
