Аннотация:Preparation of some bis(trialkylstannyl)acetylenes from the corresponding trialkylstannyl chlorides was improved. The latter interacts with reactive acid chlorides and bromides to afford intermediate 1-acyl-2-trialkylstannyl-acetylenes in quantitative conversion. The subsequent halogenation of the reaction mixture performing as a one-pot procedure gives the target 1-acyl-2- halo-acetylenes in high yields and provides an effective recycling of the expensive starting trialkylstannyl chlorides.
