Abstract
Herein, we report a manganese-catalyzed Z-selective hydroarylation of allenyl ethylene carbonates (AECs) under mild conditions. The methodology employs an earth-abundant Mn(I)-catalyst, which shows high functional group tolerance, performed at room temperature, resulting in good-to-excellent yields of the products with very high Z-selectivity. Besides, mechanistic insights reveal the substitution effects of the allenes over the control of Z-selectivity.

Abstract
Phthalimides are prevalent in numerous pharmaceuticals, prompting various phthalimide syntheses through C-H activation. Nevertheless, the necessity for stoichiometric additives limits their practicality and versatility. Herein, we introduced diethyl dicarbonate as a carbonyl source for an additive-free carbonylation of benzamides. This transformation signifies an operationally simple and CO-free phthalimide synthesis.

Abstract
Transition metal-catalyzed enantioselective C-H carbonylation with carbon monoxide, an essential and easily available C1 feedstock, remains challenging. Here, we disclosed an unprecedented enantioselective C-H carbonylation catalyzed by inexpensive and readily available cobalt(II) salt. The reactions proceed efficiently through desymmetrization, kinetic resolution, and parallel kinetic resolution, affording a broad range of chiral isoindolinones in good yields with excellent enantioselectivities (up to 92 % yield and 99 % ee). The synthetic potential of this method was demonstrated by asymmetric synthesis of biological active compounds, such as (S)-PD172938 and (S)-Pazinaclone. The resulting chiral isoindolinones also serve as chiral ligands in cobalt-catalyzed enantioselective C-H annulation with alkynes to construct phosphorus stereocenter.

Abstract
The carbonyl group forms an integral part of several drug molecules and materials; hence, synthesis of carbonylated compounds remains an intriguing area of research for synthetic and medicinal chemists. Handling toxic CO gas has several limitations; thus, using safe and effective techniques for in or ex situ generation of carbon monoxide from nontoxic and cheap precursors is highly desirable. Among several precursors that have been explored for the generation of CO gas, chloroform can prove to be a promising CO surrogate due to its cost-effectiveness and ready availability. However, the one-pot chloroform-based carbonylation reaction requires strong basic conditions for hydrolysis of chloroform that may affect functional group tolerability of substrates and scale-up reactions. These limitations can be overcome by a two-chamber reactor (COware) that can be utilized for ex situ CO generation through hydrolysis of chloroform in one chamber and facilitating safe carbonylation reactions in another chamber under mild conditions. The versatility of this "Chloroform-COware" technique is explored through palladium-catalyzed aminocarbonylation of medicinally relevant heterocyclic cores, viz., isoquinoline and quinoline.

Abstract
The merger of transition metal catalysis and photocatalysis has emerged as a versatile platform that opened the gateway to diverse low-energy pathways for several synthetic transformations. However, amidst the first-row transition metals, directed C-H bond functionalization mediated by high-valent cobalt catalysis has advanced with rising momentum owing to its unique reactivity and the ability to participate in both one- and two-electron transfer reactions. However, the use of expensive, privileged Cp* ligands or use of stoichiometric silver(I) or manganese(III) is unavoidable. Despite significant advances in their respective fields, the combination of these two "green" approaches to further the vested interest of the scientific research community towards the development of ecofriendly and sustainable protocols is noticeably limited. Thus, the methodology based on high-cobalt-photoredox dual-catalytic strategy has high dormant potential and is worthy to explore. Herein, we highlight the recent advances in the high-valent cobalt-catalyzed sustainable catalytic approach by harnessing light energy for oxidative C-H bond functionalization. With this, we hope to inspire the development of unexplored cobalt-photoredox-catalyzed reactions with improved efficiency and selectivity.

Abstract
Direct carbonylation of the C-H bond is a great tool for installing a carbonyl group in a wide variety of substrates. This review summarizes the C-H bond carbonylation methodologies using the cobalt-catalyzed C-H bond functionalization approach. Despite the fact that cobalt-catalyzed carbonylation methodologies have been known since Murahashi's report in 1955, this area is still underdeveloped, particularly carbonylation of the C(sp3)-H bond.

Abstract
The limitations of arene C-H functionalization of aryl sulfonamides containing strongly coordinating N-heterocycles were overcome using a Rh(iii) catalyst. The site-selectivity of C-H carbenoid functionalization at the ortho position relative to either the sulfonamide or N-heterocycle directing groups was elegantly switched using solvents of different polarities and different additive concentrations. Importantly, sulfonamide-group-directed ortho-C-H carbenoid functionalization tolerated strongly coordinating N-heterocycles, including pyridine, pyrrole, thiazole, pyrimidine, and pyrazine. Density functional theory (DFT) calculations were performed to rationalize the reaction mechanisms and the influence of reaction polarity.

Abstract
The carbonyl moiety is one of the indispensable sub-units in organic synthesis with significant applications in medicinal as well as materials chemistry. Hence the insertion of a carbonyl group via simple and highly efficient routes has been one of the most challenging tasks for organic chemists. Though the direct utilisation of CO gas in carbonylation is the fundamental procedure for the construction of carbonyl compounds, it has certain drawbacks due to its toxic and explosive nature. As a result, the need for cheap and efficient CO surrogates has gained much attention nowadays by which CO gas can be easily generated in situ or ex situ. In this review we discuss the advantages of chloroform as CO surrogate and have surveyed recent carbonylation reactions where chloroform has been used as CO source.
