✦ Synopsis

Pentacoordinated hydrosilanes react with excess of aryl isocyanates to give isocyanurates under mild and neutral conditions. The catalytic species are the initially formed N-silylfi~rmamides, which incorporate three equivalents of isocyanate, and then rearrange to N-silylformamide and isocyanurates.
