Abstract The direct conversion of specific C−H bonds to C−Si in alkanes or aromatics via catalytic methods has attracted growing research interest. Herein, we report the preparation a new iridium catalyst supported on naphthyridine‐based porous organic polymer and its successful application dehydrogenative silylation 2‐arylphenols alcohol hydrosilanes access ring‐fused oxasilacycles. synthetic method exhibits broad substrate scope good functional group compatibility while avoiding use hydrogen acceptors. In addition, this could be easily recovered from reaction system reused for at least seven times without apparent deactivation. This provides insights further design heterogeneous nanocatalysts contributes synthesis silicon‐substituted molecules.

Abstract Pyrrolo[1,2‐ α ]quinoxaline and its derivatives have excellent biological activity photoelectric properties, are widely used in the fields of pharmaceutical preparations organic electroluminescence. This review starts from catalysts summarizes single metal catalysis palladium, rhodium, iron, molybdenum, copper, as well synergistic iron molybdenum bimetallic metal‐free catalytic systems for synthesis pyrrolo[1,2‐ ]quinoxaline. The mechanism different was detailly introduced analysed. By analysing advantages disadvantages existing catalyst systems, prospects new methods presented.

Abstract A direct electrochemical redox reaction involving radical cross‐coupling cyclization for the synthesis of pyrrolo[1,2‐ a ]quinoxaline derivatives from 1‐(2‐aminophenyl)pyrroles and CH 3 CN has been developed, which includes functionalization C( sp )−H bonds as well construction C−C C−N bonds. Notably, control deuterium‐labelling experiments suggest that in this acts both carbon source via cleavage solvent. The features metal‐ oxidant‐free conditions, various substituted were obtained.

Abstract We describe herein a method for transition‐metal‐free (hetero)arylsulfonylation of 1‐iodopyrrolo[1,2‐ ]quinoxalines with sodium arylsulfinates. The corresponding aryl iodides were in situ prepared from eletrophilic iodination C1−H bonds pyrrolo[1,2‐ N ‐iodosuccinimide. ensuing sulfonylation only required DMSO as solvent and completed after 15 min. Many arylsulfinates bearing chloro, bromo, methylsufonyl, acetamide, nitro groups competent substrates. Heteroarylsulfonylation also feasible.
