资源简介:
Controlled hydrolysis of MeLGaCl2 (MeL = 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 [{MeLGa(OH)}2(μ-O)] (2) in high yield. Compound 2 was used in the assembly of the heterobimetallic galloxanes with group 4 metals [{(MeLGa)2(μ-O)}(μ-O)2{M(NR2)2}] (M = Ti, R = Me (6); M = Zr (7), Hf (8), R = Et).
