Abstract |
Triethylstannyldiphenylphosphine 과 phenylisocyanate를 앰푸울속에서 1 : 10 몰비로 여러온도에서 반응시켰다. 이들 반응에서, 놀랍게도 저온 반응에서 diphenylcarbodiimide가 N,N-diphenyluretidine-2,4-dione과 함께 생성되었고, 고온반응에서는 1,3,5-triphenyl-4-phenyliminohexahydro-1,3,5-triazine-2,6-dione과 N,N-diphenyluretidine-2,4-dione 및 triphenylisocyanurate가 생성되었다. 그러나 실온반응에서는 triphenylisocyanurate 만을 얻을 수 있었다. Triethylstannyldiphenylphosphine은 모든 반응에서 상기 반응생성물의 촉매로 작용하였다. Reactions of triethylstannyldiphenylphosphine with phenylisocyanate were carried out at various temperatures in sealed ampoules. At low reaction temperature, diphenylcarbodiimide was surprisingly given together with N,N-diphenyluretidine-2,4-dione, the cyclic dimer of phenylisocyanate. And 1,3,5-triphenyl-4-phenyliminohexahydro-1,3,5-triazine-2,6-dione, carbodiimide and triphenylisocyanurate which is the cyclic trimer of phenylisocyanate were formed at higher reaction temperatures. But at around the room temperatures, we could get only triphenylisocyanurate. Triethylstannyldiphenylphosphine was acted as a catalyst for the formation of the above compounds. |
