Diazo Compounds. 72. Diazoalkylphosphanes - Synthesis by Electrophilic Diazoalkane Substitution and Oxidative Addition Reactions at PhosphorusElectrophilic diazoalkane substitution of the diazomethyl compounds 1a,b with the chloro phosphanes 2a-o in the presence of lithium diethylamide yields the diazoalkyl phosphanes 3a-z. Oxidative addition of oxygen, sulfur and selenium at phosphorus leads into the series of oxo, thioxo and selenoxo phosphanes having diazoalkyl substituents (4a-d, 5a-m and 7a-d). The silyl group of 5n,o is cleaved by chromatography on aluminium oxide to yield the (diazomethyl)phosphane sulfides 6a,b.
