Disclosed is a solid catalyst comprising a solid support having deposited thereon a catalytically active composite material that is practically insoluble in a variety of liquid media, wherein the insoluble catalytically active composite material is formed by precipitating an anionically charged catalytically active entity, selected from metal complexes quaternary compounds, metal oxo anions, polyoxometallates and combinations thereof, with a group II A metal cation selected from Ca2+, Sr2+ and Ba2+, where the metal complex has the formula (M)x(L)y(L*)z, wherein: M is a catalytic metal atom or ion of a coordination complex of a transition metal from group IIIB, IVB, VB, VIB, VIIB, IB or IIB, x is from 1-60, L is aliphatic, aromatic or heterocyclic compound, Y is at least 1, L* is a radical selected from an organic anion, inorganic anion and coordinating compound, z is from 0-7, and the quaternary compound has the formula [(Y+)(R*)I][Z-], wherein: I is 4 for Y+ is N+, P+ or As+, and I is 3 for Y+ is S+, and R* is alkyl, aryl, arylalkyl, alkylaryl, alkoxy, aryloxy, or cycloalkyl.
