functionalization of amines. However, there are still several mechanistic uncertainties, particularly the factors governing the regioselectivity of the oxidation of asymmetric secondary amines and the oxidation rates of mixed primary amines. Herein, it is reported that singlet‐oxygen‐mediated oxidation of 1° and 2° amines is sensitive to the strength of the α‐CH bond and steric factors. Estimation of the

A 1D COF JNM-12 as metal-free photocatalyst for photocatalytic oxidization of benzylamine to N-benzylbenzaldimine and enamine oxidation to α-amino carbonyl compounds was reported. It exhibited high functional group tolerance and broad substrate scope achieved under mild conditions utilizing visible-light.

Morphology control of conjugated microporouspolymernetworks (CMPs) has emerged as a promising strategy for enhancing catalytic efficiency and alleviating product contamination in photocatalytic organic transformations. In this contribution, we present the rational design and synthesis of hollow CMPs (hPorSTZ and hPorDTZ) featuring benzothiadiazoles linkages via Sonogashira-Hagihara cross-coupling
