摘要：

The unusually strong Lewis basicity of the P atom and the ability to form transannular P-N interactions of various strengths account for the high catalytic activity of [P(MeNCH2CH2)3N] in the title reaction, a key step of which is shown on the right. Thus a 97% yield of triphenyl isocyanurate (Ar = C6H5) was obtained in 3 min, and a 99% yield of tri-para-methoxyphenyl isocyanurate (Ar = 4-MEOC6H4) in 8 min.
