A process for the preparation of ketones corresponding to the general Formula I
1
in which &bgr;,&ggr;,&dgr;-allenic, di-unsaturated ketones and/or &agr;,&bgr;,&ggr;,&dgr;-conjugated, di-unsaturated ketones, obtained by reaction of propargyl alcohols with enol ethers and are converted in direct manner by hydrogenation to the saturated ketones corresponding to the general Formula I without purification by distillation.
一种制备与一般式I1相对应的酮的过程,其中&bgr;,&ggr;,&dgr;-全炔基,双不饱和酮和/或&agr;,&bgr;,&ggr;,&dgr;-共轭,双不饱和酮,通过
丙炔醇与烯醇醚的反应获得,并通过氢化直接转化为与一般式I相对应的饱和酮,而无需经过蒸馏纯化。
