ABSTRACT:
Alkylidene compounds and arylidene compounds are prepared by reacting the corresponding CH-acidic compounds with carbonyl compounds in the presence of a catalyst comprising a metal compound of a metal of Groups IIA, IIIA, IVA, IB, IIB, VIB, VIIB, or VIIIB of the periodic table of elements. The rate of reaction is increased by adding 1 to 40% water referred to the weight of catalyst used.
