method for the selective synthesis of boryl ethers via O-borylation of alcohols with vinylboronates catalyzed by the Ru-H complexes [Ru(CO)C]H(PPh 3 ) 3 ] and [Ru(CO)CIH(PC Y3 ) 2 ] is described. The mechanism of catalysis of this new de-ethenative borylation is supported by equimolar reaction of Ru-B complex with alcohol.
