摘要：
Process for preparing a compound having a nonaromatic C—C double or triple bond (compound A) from another compound or a mixture of other compounds having a nonaromatic C—C double or triple bond (compound B), which comprises bringing the compound (B) into contact with a heterogeneous catalyst comprising carbides or oxycarbides of a transition element at from 50 to 500° C.
