Abstract
The present invention describes chemical systems and methods for silylating N—H bonds of aliphatic amines, said system or method comprising or consisting essentially of a mixture of (a) at least one organosilane and (b) at least one hydroxide, especially KOH, said system being preferably, but not necessarily substantially free of a transition-metal compound, and said methods comprising contacting a quantity of the organic substrate with a mixture of (a) at least one organosilane and (b) at least one strong base, under conditions sufficient to replace an N—H bond with a silyl N—Si bond.
