Abstract:

Akynyl ketones were synthesized from tetraalkinylstannanes and both aliphatic and aromatic acyl chlorides under Lewis acid catalisys. The structure of products was confirmed by means of NMR, IR, GC-MS. The method is suitable for the synthesis of long-chain acetylenic ketones.

Keywords: Organotin compounds, tetraalkynylstannanes, acyl chlorides, α,β- acetylenic ketones
