AbstractThe reaction of o-bromophenyl methyl selenide with lithium dimethyl-phosphide, -arsenide, and -antimonide gave the seleno-phosphine o-C6H4(SeMe) PMe2(2), -arsine o-C 6H4(SeMe)AsMe2 (3), and -stibine o-C 6H4(SeMe)SbMe2 (4) respectively. The seleno-amine o-C6H4(SeMe)(NMe2) (7), -ether o-C6H4(SeMe)OMe (5), and -sulphide o-C6H 4(SeMe)SMe (6) were obtained from methaneselenenyl bromide and RMgBr [R = o-C6H4(OMe), o-C6H4(NMe 2)] or o-C6H4(SMe)Li. The bis-selenide o-C 6H4(SeMe)2 (8) is conveniently prepared from the polymeric selenide -(o-SeC6H4Se)n, NaO 2SCH2OH, and MeI. The o-substituted selenides have been characterised by mass spectrometry, 1H, 13C, and 77Se n.m.r. spectroscopy, and for compounds (2), (3), (4), and (8) by the preparation of quaternary derivatives. The trends in the 77Se n.m.r. chemical shifts and coupling constants are discussed.
