| abstract | The invention provides a novel method for the synthetic preparation of an ω-haloalkyne compound of the general formula R--C.tbd.C--CH 2 ) n X, in which X is a halogen atom, R is a monovalent hydrocarbon group and n is 4, 5 or 6, by the coupling reaction of a Grignard reagent RMgX' and an ω-halo-1-bromoalkyne compound of the formula X--CH 2 ) n C.tbd.C-Br. The ω-haloalkyne compound obtained in the above can be readily converted to the corresponding alkenyl acetate of the formula R--CH═CH--CH 2 ) n OCOCH 3 by first acetylating and then partially hydrogenating in the presence of a Lindlar catalyst. In particular, 7, 11-hexadecadienyl acetate, which is a sexual pheromone compound of a noxious insect, is obtained in the same route of synthesis starting with the Grignard reagent of a 1-halo-3-octene and 1, 8-dibromo-1-octyne. |
