Abstract Herein, we have reported an effective protocol for the regioselective transfer hydrogenation (TH) of epoxides by utilizing a phosphine‐free bis‐NHC−Mn(I) complex and ammonia borane. By employing this strategy, aromatic were selectively converted to primary alcohols whereas secondary obtained exclusively from aliphatic epoxides. The was further extended TH azoarenes nitroarenes hydrazoarenes anilines respectively. Notably, library substrates with different functional groups screened which resulted in corresponding hydrogenated product good excellent yields. A series mechanistic investigations carried out understand catalytic process.

It is a great challenge to construct green catalytic system for the reduction of nitro compounds corresponding amines under mild conditions. Due low energy red light, it challenging develop photocatalytic selective nitroaromatics aromatic driven by light. A bimetallic porphyrin metal–organic framework (Bi-P(Co)MOF) was characterized Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, scanning and energy-dispersive techniques. The constructed photocatalyst Bi-PMOF-Co shows excellent activity conversion in high yields with NaBH4 as reducing agent at room temperature light irradiation. Moreover, protocol showed functional group compatibility, recyclability demonstrated five-cycle tests.
