Highly active and selective platinum(0)-carbene complexes.: Efficient, catalytic hydrosilylation of functionalised olefins

Readily available N-heterocyclic platinum-carbene complexes 1 are highly efficient catalysts for the regioselective hydrosilylation of alkenes. These novel organometallics tolerate a wide range of functional and protecting groups, can be stored for prolonged periods of time and are particularly active (TON > 10(6)).
