Isomerization of allenes to alkynes with an alkaline-earth metal hydride containing catalyst

摘要

Providing an isomerization process which can isomerize allenes to alkynes less expensively and stably is an assignment to be solved by the present invention and given thereto. The present invention is an isomerization process including the step of reacting an allene-lype hydrocarbon compound (R1R2C=C=CR3R4) in the presence of alkaline-earth metal hydride working as an isomerization catalyst, thereby isomerizing the allene-type hydrocarbon compound to an alkyne-type hydrocarbon compound (R1C=C-CR2R3R4).
