    摘要： Disclosed is a novel ene-yne compound Z-12-heptadecen-1-yne expressed by the structural formula CH.sub.3 (CH.sub.2).sub.3 CH.sup.(Z) =CH(CH.sub.2).sub.9 C=CH, which is useful as an intermediate in the synthetic preparation of several diene compounds having activity as a sex pheromone of the insects belonging to the lepidopteran order, such as E,Z-2,13-octadecadienyl acetate and E,Z-2,13-octadecadienal, having two double bonds at the 2- and 13-positions. The inventive compound can be synthesized by the reaction of 1-bromo-Z-10-pentadecene with sodium acetylide dispersed in an organic solvent in the presence of liquid ammonia.

    摘要： Proposed is a novel and very efficient method for the preparation of an N-vinyl compound such as N-vinyl-2-pyrrolidone and N-vinyl-N-ethyl acetamide by the thermal decomposition of an N-(.alpha.-acyloxyethyl) compound which is a novel compound obtained by the addition reaction between an NH group-containing compound such as 2-pyrrolidone and N-ethyl acetamide and a vinyl carboxylate, e.g., vinyl acetate, in the presence of an alkali, e.g. alkali metal hydroxide. The reaction mixture after completion of this addition reaction as such, i.e. without isolating the N-(.alpha.-acyloxyethyl) compound, such as N-(.alpha.-acetoxyethyl)-2-pyrrolidone and N-(.alpha.-acetoxyethyl)-N-ethyl acetamide, is heated to effect in situ formation of the desired N-vinyl compound which can then be isolated by distillation under reduced pressure in a very high overall yield.
