Catalysis of dehydrocoupling reactions between amines and silanes
A method for dehydrocoupling silanes and amines. The method comprises contacting: (a) an aliphatic amine; (b) a silane; and (c) a catalyst which is ZnX 2 , wherein X is alkyl, chloride, bromide, iodide, trifluoromethanesulfonate, bis(trifluoromethane)sulfonamide, tosylate, methanesulfonate or O 3 S(CF 2 ) x CF 3 wherein x is an integer from 1 to 10.
1. A method for dehydrocoupling silanes and amines; said method comprising contacting: (a) an amine; (b) a perhydridosilane; and (c) a catalyst which is ZnX 2 , wherein X is alkyl, chloride, bromide, iodide, trifluoromethanesulfonate, bis(trifluoromethane)sulfonamide, tosylate, methanesulfonate or O 3 S(CF 2 ) x CF 3 wherein x is a integer from 1 to 10.
2. The method of claim 1 in which the perhydridosilanes has from 1 to 10 silicon atoms.
3. The method of claim 2 in which the amine has only one hydrogen atom bonded to a nitrogen atom and has from 2 to 20 carbon atoms.
4. The method of claim 3 in which (a), (b) and (c) are heated at a temperature from 40 to 180° C.
