Abstract
Novel platinum/olefin complexes, useful for the hydrosilylation curing catalysis of hardenable organopolysiloxane compositions, are facilely prepared by reacting a platinum halide with at least one alkali or alkaline earth metal carbonate or bicarbonate in the presence of an alkenylcyclohexene ligand having the general formula: ##STR1## wherein R.sub.1 is an alkenyl radical having from 2 to 6 carbon atoms, and R.sub.2 is a hydrogen atom or an inert organic radical, and said complex having a ratio, in gram-atoms of halogen to gram-atoms of platinum, ranging from virtually 0 to 4.
