Abstract
A process for preparing isocyanoatoorganosilanes by thermolysis of carbamatoorganosilanes in the presence of microwave radiation, optionally employing homogeneous or heterogeneous catalysis, provides isocyanatoorganosilane product in higher yield than prior art thermolyses, and with fewer byproducts. A continuous process is thus possible.
