Abstract
The nonclassical trihydride [Ru(tdpep)(H)(H2)]BPh41 catalyses under mild conditions the chemoselective reduction of α,β-unsaturated ketones to allylic alcohols via hydrogen-transfer [tdpep = P(CH2CH2PPh2)3]; compound 1 reacts with acyclic ketones (or aldehydes) yielding stable η2-carboxylate complexes of general formula [Ru(tdpep)(O2CR)]BPh4, and ethers (or ethers plus esters).Keywords
