A Synthetic Route to a Molecular Galloxane Dihydroxide and Its Group 4 Heterobimetallic Compounds
Controlled hydrolysis of (LGaCl2)-L-Me (L-Me = HC[(CMe)N(2,4,6-Me3C6H2)](2)(-)) (1) in the presence of a N-heterocyclic carbene, as a HCl acceptor, led to the unprecedented molecular galloxane dihydroxide [{(LGa)-L-Me(OH)}(2)(mu-O)] (2) in high yield. Compound 2 was used in the assembly of the heterobimetallic galloxanes with group 4 metals [{((LGa)-L-Me)(2)(mu-O)}(mu-O)(2){M(NR2)(2)}] (M = Ti, R = Me (6); M = Zr (7), Hf (8), R = Et).
