A quantitative procedure for the hydrosilylation of allylic −SiMe3 protected phenols with Et3SiH and Si−H terminated carbosilane dendrimers of first, second, and fourth generations have been performed to give nG-[(CH2)3{C6H4-r(OMe)r}OH]m. The subsequent treatment with [Ti(C5Me5)Cl2Me], [Ti(C5Me5)Me3], or [M(C5H5)2ClX] (M = Ti, X = Cl; M = Zr, X = H) afforded the corresponding organometallic metallodendrimers.
