Abstract
Abstract Compounds of tricoordinate phosphorus are well known to have the ability to exchange some reactive groups bound to the P(II1) centre (scheme 1) or they may exchange reactive groups in result of the interaction with compounds of other heteroatoms like silicon (scheme 2) Particularly remarkable reactivity and often amazingly high selectivity are exhibited by systems involving R1 and R2 substituents increasing nucleophilicity of the phosphorus centre like dialkylamine groups. It was shown that in these systems ionic complexes are formed (scheme 3,4) which are stable on the NMR time scale at low temperatures. Variant temperature 31p and 29Si NMR studies of these complexes proved that they are true intermediates in the ligand exchange processes.
