摘要

Several g1-complexes of 2,4,6-tritertiarybutylphosphabenzene, PC5H2But 3, have been synthesised and structurally characterised including trans-[PtCl2(PEt3)(g1-PC5But 3)], cis-[PdCl(C10H6CHMe(NMe2)(g1- PC5H2But 3)] and [AuCl(g1-PC5H2But 3)]. NMR spectroscopic evidence is presented for the partial isomerisation in solution of the 2,4,6-tritertiarybutyl-1,3,5-triphosphabenzene complexes trans-[PtCl2(PR3)(g1- P3C3But 3)], (PR3 = PMe3 and PMe2Ph), to the corresponding cis-isomers
