Mode opératoire

In analogy to Example 6, a reaction mixture consisting of 640 g of p-xylene, 680 g (8.17 mol) of allyl isocyanate and 1250 g (7.6 mol) of triethoxysilane was reacted at from 76° to 92° C. over the course of 150 minutes. Working up by distillation gave 1350 g of 3-isocyanatopropyltriethoxysilane in addition to the trimer.
