Shvo's catalyst
Did you know?
The Shvo catalyst is an organoruthenium compound that catalyzes the hydrogenation of polar functional groups including aldehydes, ketones and imines. The compound is of academic interest as an early example of a catalyst for transfer hydrogenation that operates by an "outer sphere mechanism". … See more The catalyst is named after Youval Shvo, who uncovered it through studies on the effect of diphenylacetylene on the catalytic properties of triruthenium dodecacarbonyl. The reaction of diphenylacetylene and Ru3(CO)12 gives the See more In the presence of a suitable hydrogen donor or hydrogen gas, Shvo's catalyst effects the hydrogenation of several polar functional groups, e.g. aldehydes, ketones, imines, and iminium … See more Shvo's catalyst facilitates the Tishchenko reaction, i.e., the formation of esters from alcohols.
