  • Method for the synthesis of isocyanates
    Patent number: 12559452
    Abstract: The invention relates to a method for the preparation of isocyanates. Here it is provided that (i) a first organosilicon compound having at least one silicon atom Si1 and a unit of formula G-I bound thereto is converted to a third organosilicon compound having a unit of formula G-II by silylation of the NH group of the unit of formula G-I with a second organosilicon compound having one silicon atom Si2; and (ii) the third organosilicon compound is reacted to an isocyanate by thermolysis, whereby the unit of formula G-II is converted to an isocyanate group.
