Synthesis and characterization of a series of trans-[(CO)5M{Ph2PX(CH2)3NCHC6H4-o-O}]2M′ (M = Mo; X = NH or M = Cr, W; X = CH2; M′ = Ni, Cu, Zn) complexes and the X-ray crystal structure of trans-[(CO)5MO{P(OCH2CMe2CH2O)NH(CH2)2-NCHC6H4-o-O}]2Cu

starting from the corresponding secondary phosphines in an easy three step synthesis. All new compounds were characterized by their 1H -, 13C and 31P NMR data. Some of these new P, N ligands were used to prepare complexes [R2P- (CH2)n-CN}2PdCl2] which were also identified by their NMR data. In addition the crystal structures of three derivatives, [ipr2P-(CH2)3-CN}2PdCl2] 7a, [ph2P-(CH2)3-CN}2PdCl2)
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
we report a catalyst-free reaction of cyclobutanone oximes with chlorophosphines (R2PCl), which forms a fragile C═N–O–PR2 species that undergoes N–O homolysis, fragmentation, and radical–radical coupling, leading to the formation of cyano-containing phosphine oxides in good yields. The reaction features an in situ activation of cyclobutanone oximes for radical generation, in which R2PCl plays a dual
