用乙炔与溴乙基镁在四氢呋喃溶剂中反应以制得溴乙炔镁.将此试剂在低温时与α,β-不饱和酮起反应,制成几种烯炔醇,得到满意的产率.这些产物是合成维生素甲的重要中间体.

Ethynylmagnesium bromide was prepared by reaction of acetylene with ethylmagnesium bromide in tetrahydrofuran. With this Grignard reagent and α,β-unsaturated ketones at low temperature, we obtained several vinylacetylenic alcohols with satisfactory yields. These alcohols are important intermediates in the synthesis of vitamin A.
