Abstract

1,194,940. 4-Pentene nitrites. E. I. DU PONT DE NEMOURS & CO. 31 Oct., 1968 [1 Nov., 1967], No. 6315/70. Divided out of 1,194,939. Heading C2C. 4-Pentene nitriles are obtained by isomerizing 3-pentene-nitriles by contact with palladium or platinum compounds in which the valence of the metal is + 2 or less, at - 25‹ to 200‹ C. Specified catalysts are palladium dihalides and compounds of the formula M(PX 3 ) 4 , where M is palladium or platinum atom and X is OR or R, R being an alkyl group or an aryl group having up to 18 carbon atoms, and wherein any of the X's may be cojoined. The catalyst, which may be prior prepared or formed in situ, may also contain a promoter, many types of which are specified, and/or an acid.
