摘要：

Diphenyltrimethylsilylphosphine was found to be an effective catalyst for cyclization of phenyl isocyanate, affording cyclic dimer and trimer at moderate temperature. An abnormal decarboxylation took place to give diphenylcarbodi- imide and its cyclic trimer above 50°. Evidence for the equilibrium reaction, 3 diphenylcarbodi-imide ⇌ cyclic trimer, was obtained. Phenylbis(trimethylsilyl)phosphine forms a stable 1:1 adduct with phenyl isocyanate; its structure is discussed.
