A binary catalyst system of a cationic Ru-CNC pincer complex with an alkali metal salt for selective hydroboration of carbon dioxide

© The Royal Society of Chemistry 2016.Binary catalyst systems comprising a cationic Ru-CNC pincer complex and an alkali metal salt were developed for selective hydroboration of CO2 utilizing pinacolborane at r.t. and 1 atm CO2, with the combination of [Ru(CNCBn)(CO)2(H)][PF6] and KOCO2tBu producing formoxyborane in 76% yield. A bicyclic catalytic mechanism was proposed and discussed.Link_to_subscribed_fulltex
