Regioselective hydrostannations catalyzed by molybdenum isonitrile complexes

Hydrostannations using Mo(CO)3(CNtBu)3 give rise to α-stannylated alcohols and ethers in a highly regioselective fashion. The yields and selectivities obtained with this catalyst are significantly higher in comparison to the results obtained with the commonly used palladium and rhodium catalysts. The influence of the isonitrile incorporated into the molybdenum complex is investigated.
