The Reaction of Trimethylsilylamines and Trimethylstannylamines with Phenylisocyanate

Trimethylsilylamine 및 Trimethylstannylamine 과 Phenylisocyanate 와의 반응
Ghap-Ju Ghim, Il-Kyu Lee

Trimethyldiethylaminosilane, trimethylanilinosilane, trimethyldiethylaminostannane 및 trimethylanilinostannane 을 phenylisocyanate와 20, 50, 100 및 150℃에서 각각 3일간 반응시켰다. 모든 경우, 100℃ 이하에서는 triphenylisocyanurate만이, 150℃ 이상에서는 triphenylisocyanurate와 함께 diphenylcarbodiimide도 상당량 생성되었다. 그 반응속도는 silane의 경우는 anilino 화합물이 diethylamino 화합물보다 빨랐으나, stannane의 경우에는 anilino 화합물이 diethylamino화합물보다 오히려 늦었다.

Trimethyldiethylaminosilane, trimethylanilinosilane, trimethyldiethylaminostannane and trimethylanilinostannane were reacted with phenylisocyanate at various temepturares. All the reactions below l00℃ gave only triphenylisocyanurate, but above 150℃, diphenylcarbodiimide also was produced considerably. The reaction rate of anilinosilane was faster than that of aminosilane, but in the case of stannanes, the amino compound was more reactive.
