Reaction of MP(Ph)SiMe2But (M = Li, K) with an equivalent of PhCN afforded the 1-aza-3-phosphaallyllithium and -potassium complexes [M{P(Ph)C(Ph)NSiMe2But}(L)]2 (1, M = Li, L = THF; 2, M = K, L = Et2O), respectively. After exposing 2 in vacuo at room temperature, the solvent-free complex [K{P(Ph)C(Ph) NSiMe2But}] (3) was obtained. Treatment of 1 with SnCl2 in a 2:1 ratio furnished the homoleptic tin(II) complex [Sn{P(Ph)C(Ph)NSiMe2But}2] (4). Compound 1 reacted with an equimolar amount of ClSnN (SiMe3)2 to give [P(Ph)C(Ph)=NSiMe2But]2 (5) via ligand coupling. Reaction of 3 with PhCN produced [K{P(Ph)C(Ph)NC(Ph)NSiMe2But}] (6) by addition of the nitrogen atom to PhCN followed by a 1,3-N0→N′ migration of the SiMe2But group. Structures of compounds 1, 2, 4 and 5 have been determined by single crystal X-ray diffraction techniques. The complexes 1 and 2 are dimeric and 4 is both monomeric, while 5 is the product of a ligand coupling with formation of new P-P bond.
