A catalytic, light-promoted hydrosilylative cleavage reaction of alkylethers is reported. Initial studies are consistent with a mechanism involving heterolytic silane activation followed by delivery of a photohydride equivalent to a silyloxonium ion generated in situ. The catalyst resting state is a mixture of Cp*Ir(ppy)H (ppy = 2-phenylpyridine-κC,N) and a related hydride-bridged dimer. Trends in

conversion of alkyl ethers to silylethers via C–O bond cleavage. The previously-reported cationic pincer-supported iridium complex for this transformation suffers from poor selectivity with regard to monodealkylation of substrate ethers. We demonstrate that a simple non-pincer iridium complex offers improved selectivity and is capable of benzylic ether cleavage in the presence of reductively-labile
