摘要:
Reaction of 2 equiv of AlMe3 with 1,2-C6H4{NHC(t-Bu)O}(2) gives the tetranuclear aluminum compound [{AlMe2(1,2-C6H4{NC(t-Bu)O}(2))}AlMe2](2) (1), the molecular structure of which exhibits a novel central 16-membered ring formed by four AlMe2 units and four NCO fragments. Treatment of 1 with 1 equiv of B(C6F5)(3) affords the ionic species [{(AlMe2)(3)(AlMe)(1,2-C6H4{NC(t-Bu)O}(2))(2)][MeB(C6F5)(3)] (2).
