N2 - Hydrosilanes act as a reagent to cleave the C-O bond of OtBu groups in carbamates, carbonates, esters, and ethers by catalysis of a triruthenium cluster. The reaction offers a novel deprotection method, for OiBu groups under neutral conditions, showing unique selectivities that have never been accomplished with conventional Bronsted or Lewis acidic promoters. Possible mechanisms for C-O cleavage are discussed on the basis of NMR spectroscopic analysis.
