报道了二价配合物 ( CH3C5H4) 2 Sm( THF)和 Sm I2 ( THF) x 与异氰酸苯酯的反应 . ( CH3C5H4) 2 Sm( THF)和异氰酸苯酯反应生成配合物 [( CH3C5H4) 2 ( THF) Sm]2 [μ-η4-( Ph N) OCCO( NPh) ]· 2 THF( 1 ) ,而Sm I2 ( THF) x则被异氰酸苯酯氧化为 [Sm I2 ( THF) 5][Sm I4( THF) 2 ]. ( CH3C5H4) 2 Sm( THF)和配合物 1都能催化异氰酸苯酯的齐聚反应 .( CH3C5H4) 2 Sm( THF)和异氰酸苯酯作用生成配合物 1的反应可以认为是( CH3C5H4) 2 Sm( THF)催化异氰酸苯酯齐聚的引发反应 ,而配合物 1是该齐聚反应的活性中间体 . X射线衍射分析表明 ,配合物 1是一个由草酰胺双负离子桥联的双金属化合物
The reaction of divalent complexes (CH3C5H4) 2 Sm (THF) and Sm I2 (THF) x with phenylisocyanate was reported. The reaction of (CH3C5H4) 2 Sm (Ph) OCCO (NPh)] · 2 THF (1) and Sm I2 (THF) x is oxidized by phenylisocyanate to [Sm I2 (CH3) (CH3C5H4) 2 Sm (THF) and complex 1 can catalyze the oligomerization of phenyl isocyanate. (CH3C5H4) 2 Sm (THF) and isocyanic acid The reaction of phenyl ester to form complex 1 can be considered as the initiating reaction of (CH3C5H4) 2 Sm (THF) to catalyze the oligomerization of phenylisocyanate, while complex 1 is the active intermediate of this oligomerization reaction. It is indicated that complex 1 is a bimetallic compound bridged by oxalamide dianion
