reaction of transition metal boryl complexes of the type Cp*M(CO)nB(OR)2 (M = Fe, Ru, W) with alkanes to form alkylboronate esters in yields as high as 85% for reaction of Cp*W(CO)3[Bcat(Me)2] [Bcat(Me)2] = B-1, 2-O2C6H2-3, 5-Me2} with pentane. Synthesis of a series of Cp and Cp* catecholboryl complexes showed that sterically blocking or eliminating sp2 positions on the metal boryl complex was important for
