Abstract


We have prepared ruthenium complexes containing the Bbutcat2- anion (butcat = 3,5-di-tert-butylcatecholato) and the first single crystal X-ray diffraction study of a ruthenium arylspiroborate complex is presented. These new ruthenium complexes have been examined for their ability to catalyse the addition of diorganyloxyboranes to vinylarenes, and results suggest that these compounds generate the corresponding alkenylboronate esters via a competing dehydrogenative borylation pathway
