Here we report catalytic asymmetric hydrophosphination of α,β-unsaturated carbonyl derivatives using a chiral Mn(I) complex as a catalyst. Through H–P bond activation, various phosphine-containing chiral products can be accessed via hydrophosphination of various ketone-, ester-, and carboxamide-based Michael acceptors.
iron-catalyzed C(sp3)–H phosphorylation reaction enabled by a photoinduced ligand-to-metal charge transfer (LMCT) process. The reaction exhibits remarkably broad substrate scope (>66 examples), including various alkanes, halides, ketones, esters, nitriles, ethers, thioethers, and silanes as viable substrates. Notably, unconventional site selectivity of C–H phosphorylation is achieved, with the occurrence of
