Synthesis and Structure of the First Oligomeric Cyclic Dimethylsilyl-Substituted CarbodiimideNew oligomeric cyclic silylcarbodiimides 1-3 are synthesised by the reaction of the respective dichlorosilanes with cyanamide. From the resulting reaction mixture with dichloro-dimethylsilane the tetrameric compound of the hypothetical [(CH3)2Si=N-CN] is isolated. In this molecule sixteen atoms build a nearly planar ring structure with a special steric arrangement of the groups. This oligomeric silylcarbodiimides present a new kind of precursors for the pyrolytic synthesis of ceramics in the ternary system SiCN.
