Monocyclic silyl-substituted titanium amides of the general formula Z2TiL2 where L2 is a bidentate ligandNMeSiMe2YSiMe2NMe(Y , NMe, O, CH2, Z NMe2, NEt2, F, Cl, Br) have been prepared either by the reaction of the dilithiated ligand Li2L2 with the appropriate halide Z2TiHal2 or by the cleavage of the spiro compound Ti(L2) with TiZ4. With the exception of the difluoride L2TiF2 all compounds
一般式Z的单环的甲硅烷基取代的钛酰胺2 TIL 2,其中L 2为双齿ligandNMeSiMe 2 YSiMe 2 NMe(Y,NME,O,CH 2,ZNME 2,净2(F,Cl,Br)可以通过二锂化的配体Li 2 L 2与适当的卤化物Z 2 TiHal 2反应或通过螺环化合物Ti(L 2)与TiZ 4的裂解来制备。除了二氟化物L 2 TiF 2所有化合物均为单体,并具有足够的热稳定性,可在真空中蒸馏或升华。二氟化物通过TiFTi桥缔合。所有化合物的特征在于1 H(和19 F)NMR光谱以及IR和拉曼光谱。已经确定了大多数骨骼伸展振动。
