Abstract
Practical synthetic applications of catalytic decarboxylation in producing useful molecules are limited. We report herein the cationic Ir-catalyzed decarboxylations of various electron-rich and -poor aromatic carboxylic acids to produce hydrocarbons in good yield (up to >99%). Additionally, this reaction is applicable in decarboxylative hydroarylation of bicyclic alkenes and decarboxylative fluorination, indicating the potential utility of this catalytic decarboxylation in synthetic chemistry.

Abstract
Pyridine is a crucial heterocyclic scaffold that is widely found in organic chemistry, medicines, natural products, and functional materials. In spite of the discovery of several methods for the synthesis of functionalized pyridines or their integration into an organic molecule, new methodologies for the direct functionalization of pyridine scaffolds have been developed during the past two decades. In addition, transition-metal-catalyzed C-H functionalization and rare earth metal-catalyzed reactions have flourished over the past two decades in the development of functionalized organic molecules of concern. In this review, we discuss recent achievements in the transition-metal and rare earth metal-catalyzed C-H bond functionalization of pyridine and look into the mechanisms involved.

Abstract
Ring substitution reactions of nitroarenes remain an under-developed area of organic synthesis, confined to the narrow domains of SNAr and SNArH reactions. While searching for alternative methodologies, we took stock of the C-H activation reactions of nitroarenes which unearthed a variety of examples of nitro directed regioselective C-H functionalization reactions such as ortho-arylation, -benzylation/alkylation, and -allylation, oxidative Heck and C-H arylation reactions on (hetero)aromatic rings. A collective account of these reactions is presented in this review to showcase the existing landscape of C-H activation reactions of nitroarenes, to create interest in this field for further development and propagate this strategy as a superior alternative for ring substitution reactions of nitroarenes. The prospect of merging the C-H activation of nitroarenes with C-NO2 activation, thereby harnessing NO2 as a transformable multitasking directing group, is also illustrated.

Abstract
Quinoline is a versatile heterocycle that is part of numerous natural products and countless drugs. During the last decades, this scaffold also became widely used as ligand in organometallic catalysis. Therefore, access to functionalized quinolines is of great importance and continuous efforts have been made to develop efficient and regioselective synthetic methods. In this regard, C-H functionalization through transition metal catalysis, which is nowadays the Graal of organic green chemistry, represents the most attractive strategy. We aim herein at providing a comprehensive review of methods that allow site-selective metal-catalyzed C-H functionalization of quinolines, or their quinoline N-oxides counterparts, with a specific focus on their scope and limitations, as well as mechanistic aspects if that accounts for the selectivity.

Abstract
![]()
Constructing products of high synthetic
value from inexpensive and abundant starting materials is of great
importance. Aryl iodides are essential building blocks for the synthesis
of functional molecules, and efficient methods for their synthesis
from chemical feedstocks are highly sought after. Here we report a
low-cost decarboxylative iodination that occurs simply
from readily available benzoic acids and I2. The reaction
is scalable and the scope and robustness of the reaction is thoroughly
examined. Mechanistic studies suggest that this reaction does not
proceed via a radical mechanism, which is in contrast to classical
Hunsdiecker-type decarboxylative halogenations. In addition,
DFT studies allow comparisons to be made between our procedure and
current transition-metal-catalyzed decarboxylations. The utility
of this procedure is demonstrated in its application to oxidative
cross-couplings of aromatics via decarboxylative/C–H
or double decarboxylative activations that use I2 as the terminal oxidant. This strategy allows the preparation of
biaryls previously inaccessible via decarboxylative methods
and holds other advantages over existing decarboxylative oxidative
couplings, as stoichiometric transition metals are avoided.

Abstract
The beginning of the 21st century has seen tremendous growth in the field of decarboxylative activation. Benzoic acid derivatives are now recognised as atom-economic alternatives to traditional cross-coupling partners, and they also benefit from being inexpensive, readily available and shelf-stable reagents. In this microreview we discuss recent developments in the coupling of benzoic acid derivatives either with an arene or with a second benzoic acid derivative, a process often termed decarboxylative oxidative cross-coupling. These procedures offer great promise for the development of highly selective and atom-economic cross-couplings.

Abstract
This review summarizes recent developments in the C-H-functionalization of the distal positions of pyridines, quinolines and related azaheterocycles. While the functionalization of the C2 position has been known for a long time and is facilitated by the proximity to N1, regioselective reactions in the distal positions are more difficult to achieve and have only emerged in the last decade. Recent advances in the transition metal-catalyzed distal C-H-functionalization of these synthetically-important azaheterocycles are discussed in detail, with the focus on the scope, site-selectivity and mechanistic aspects of the reactions.

Abstract
A straightforward method for direct decarboxylative arylation of 1- and 3-carboxy isoquinaldic acid N-oxides with aryl iodides is reported. The reaction proceeded selectively at the carboxy function site to exclusively give the corresponding C-1 or C-3 arylated product. This methodology tolerates various aryl iodides substituted by electronically different groups. Combined with subsequent Reissert-Henze chlorination and SNAr amination, the decarboxylative arylation provides an efficient access to 1,3-functionalized isoquinoline-based antitumor agent.

Abstract
![]()
We
report herein a palladium-catalyzed C–H arylation of
quinoline N-oxides that proceeds with high selectivity
in favor of the C8 isomer. This site selectivity is unusual for palladium,
since all of the hitherto described methods of palladium-catalyzed
C–H functionalization of quinoline N-oxides
are highly C2 selective. The reaction exhibits a broad synthetic scope
with respect to quinoline N-oxides and iodoarenes
and can be significantly accelerated to subhour reaction times under
microwave irradiation. The C8-arylation method can be carried out
on a gram scale and has excellent functional group tolerance. Mechanistic
and density functional theory (DFT) computational studies provide
evidence for the cyclopalladation pathway and describe key parameters
influencing the site selectivity.
