3-(hexenyloxy)-propane-nitrile, its production and use

摘要

The 3-(hexenyloxy)-propane-nitriles of general formula A, in which R1 and R2 are optionally a hydrogen atom or a methyl group and R3 is an unbranched hexenyl group, are new and are useful as odour materials such as ingredients for perfume compositions. Their production is carried out through the base catalysed addition of acrylonitrile or methyl substituted acrylonitrile to the unbranched hexenol, in which the reaction temperature is between 0 degrees and 50 degrees C. (for acrylonitrile especially between 0 degrees and 10 degrees C., for crotonitrile especially between 15 degrees and 25 degrees C. and for methacrylonitrile, especially between 30 degrees and 40 degrees C.), and the aforesaid base is benzyl trimethylammonium hydroxide (Triton B).
