Phosphorus-nitrogen bonds exchange

Nitrogen and Phosphorus Derivatives of Bivalent Tin and Lead. Following the first syntheses of tin(ii)- and lead(ii)-nitrogen bonds in 1974, Zeldin has reported the preparation and properties of bis(dimethylamino)tin(n). The compound is a white crystalline solid which is dimeric in cyclohexane solution, but monomeric in the vapour. Variable-temperature n.m.r. studies in chlorobenzene solution indicate exchange of dimethylamino-groups between bridge and terminal positions of the dimer structure (77). With pyridine, a 1 1 adduct is formed alcohols and... [Pg.249]
