The radical 1,4-functionalizations of 1,3-enynes have emerged as a powerful strategy for the synthesis multisubstituted allenes. However, phosphorus-centered radical-initiated transformations remain largely elusive. Herein, visible-light photoredox catalytic regioselective hydrophosphinylation with diaryl phosphine oxides phosphinoyl precursors has been realized. This protocol features mild conditions, wide substrate scope, and good functional group tolerance, producing diverse range phosphinoyl-substituted allenes in moderate to yields high atom economy. Detailed mechanistic experiments revealed radical-polar crossover process reaction.

Abstract A visible‐light‐induced deuterodichloromethylation of alkenes was developed with readily available and inexpensive deuterochloroform as the reagent. Silacarboxylic acids, which could generate silyl radicals through efficient decarboxylation, were applied halogen atom transfer agents. series deuterium‐containing gem ‐dichloroalkanes prepared in good yields.

Abstract An operationally simple and mild protocol for the visible‐light‐induced intermolecular coupling of silacarboxylic acids with sulfonyl alkynes to form alkynylsilanes is presented. This study highlights use inexpensive readily available 4CzIPN as a photocatalyst, along more stable silyl radical precursors, enabling synthesis variety in good excellent yields, notably without need transition metals. The transformation offers several key advantages, including broad substrate scope, functional group tolerance, compatibility heterocyclic substrates. Furthermore, both scale‐up reaction late‐stage functionalization natural products have been successfully achieved under conditions. These features make process not only efficient but also versatile suitable wide range applications chemical modification.
