The syntheses of various aliphatic, aromatic, sterically hindered, and cyclic organophosphorus compounds (phosphorous acid esters, esters chlorides and ester amides, hydrogen phosphites, phosphinates and phosphates) are reported, and general procedures for preparation are given.The compounds synthesized were investigated by means of 31P-, 1H- and 13C-n.m.r. spectroscopy, and the chemical shifts measured are listed.

The reaction mechanism of 2-amido-1,3,2-benzodioxaphospholes (1) with cumyl and t-butylhydroperoxide has been studied kinetically by means of 31P-n.m.r. and e.p.r. spectroscopy and high pressure liquid chromatography. 1 reacts with cumyl hydroperoxide to give the corresponding 2-oxides (2) which with more hydroperoxide and/or water form the phosphate esters 7 and 8.These acidic phosphates decompose cumyl hydroperoxide catalytically giving phenol and aceton.All amides (1) react with t-butyl hydroperoxide stoichiometrically to give t-butanol.The ionic mechanism of hydroperoxide decomposition is accompanied in a minor proportion by a homolytical one.
