Abstract
The syntheses and characterization of two types of complexes having a metal-Salan ligand stoichiometry of 2:1 (where Salan = N,N′-bis(o-hydroxybenzyl)-1,2-diaminoethane (SaleanH4), N,N′-bis(o-hydroxybenzyl)-1,2-diaminobenzene (SalophanH4), and N,N′-bis(o-hydroxybenzyl)-1,2-diamino-(4,5-dimethyl)benzene (SalomphanH4)) are reported. The first are designated type I and are of the general formula LHAlR(AlR2), where L = Salean [R = Me (1), Et (2), iBu (3)], Salophan [R = Me (4), Et (5), iBu (6)], and Salomphan [R = Me (7), Et (8), iBu (9)]. Formed by the thermolysis of RH from the type I complexes, the type II complexes are of the general formula [LA1(A1R2)]2, where L = Salophan [R = Me (10), iBu (11)] and Salomphan [R = Me (12), iBu (13)]. The type I complexes can be converted into the trimetallic derivatives SalanAlR(AlR2)2 (type III) through the addition of AlR3 while the type II cannot. One structurally characterized trimetallic complex, SalophanAlEt(AlEt2)2 (14), serves as a representative of this successful transformation.
