摘要: Reactions of coordinatively unsaturated Ru[N(Ph2PQ)2]2(PPh3) (Q = S (1), Se (2)) with pyridine (py), SO2, and NH3 afford the corresponding 18e adducts Ru[N(Ph2PQ)2]2(PPh3)(L) S, L (5); Q Se, py (3), SO2 (4), (6)). The molecular structures complexes 2 6 are determined. geometry around Ru in is pseudo square pyramidal PPh3 occupying apical position, while that pseudooctahedral mutually cis. Ru−P distances 2.2025(11) 2.2778(11) A, respectively. Ru−N bond length 2.185(3) A. Treatment 1 or substituted hydrazines NH2OH yields respective NH2NH2 (12), t-BuNHNH2 (14), 1-aminopiperidine (C5H10NNH2) (15); PhCONHNH2 (7), PhNHNH2 (8), (9), (10), C5H10NNH2 (11), (13)), which isolated as mixtures their trans cis isomers. cis-14 cis-15 characterized by X-ray crystallography.
