Abstract

111 derivatives of the polykis(diphenylphosphino)benzenes, (Ph2P)nC6H6-n [n=2 to 4] obtained by oxidation or reaction with sulfur, selenium, iodomethane, M(CO)6 [M=Cr, Mo, W], [codRh-μ-Cl]2, or (PhCN)2MCl2 [M=Pd, Pt], are reported together with their 31P and selected other NMR parameters. The reactions generally follow predictable courses, although stereochemical factors affect the range of products obtained and can lead to significant structural distortion in extreme cases. The 31P chemical shifts and more particularly vicinal coupling constants are also markedly influenced by such factors, to the extent that in species with three or more adjacent Ph2P moieties they may be of limited diagnostic value. © Elsevier Science Ltd.
