dc.description.abstractA novel [4+2] cycloaddition reaction between osmium alkenylcarbyne complex [OsHCl2{?CC(PPh3)?CHPh}(PPh3)2]+BF4- (1) and nitriles (acetonitrile and benzonitrile) provided metallapyridiniums [OsCl2{?CHC(PPh3)?CPhCR?NH}(PPh3)2]+BF4- (R=CH3 (2), Ph (3)) and OsCl3{?CHC(PPh3)?CPhCPh?NH}(PPh3) (4). A possible mechanism was proposed. Treatment of 2 with n-BuLi and NEt3 afforded osmapyridines OsCl2{?CHC(PPh3)?CPhCCH3?N}(PPh3)2 (5) and [OsCl{?CHC(PPh3)?CPhCCH3?N}(C6H5N)(PPh3)2]+BF4- (6). The ligands of osmapyridiniums 2 and 4 were changed, thus providing a series of osmapyridiniums [OsCl(SCN){?CHC(PPh3)?CPhC(CH3)?NH}(PPh3)2]+Cl- (7), OsCl(SCN)2{?CHC(PPh3)?CPhC(CH3)?NH}(PPh3) (8), Os(SCN)3{?CHC(PPh3)?CPhC(CH3)?NH}(PPh3) (9), [OsCl{?CHC(PPh3)?CPhC(CH3)?NH}(CH3CN)(PPh3)2]+(BF4-)2 (10), [OsCl{?CHC(PPh3)?CPhC(CH3)?NH}-(?2-1,10-phenanthroline)(PPh3)]+(BF4-)Cl- (11), [OsCl{?CHC(PPh3)?CPhC(CH3)?NH}(?2-8-hydroxyquinoline) (PPh3)]+BF4- (12), and [Os{?CHC(PPh3)?CPhCPh?NH}(CH3CN)3(PPh3)]+(BF4-)3 (13). Most of these products were characterized by NMR spectroscopy, elemental analysis and single crystal X-ray diffraction.zh_CN
