N2 - The synthesis and structures of aluminum complexes incorporating bulky thioamidate (RC(NR′)S-), thioureido (R′HNC(NR′)S-), and amidinate (RC(NR′)-2) ligands are described. The reaction of AlMe3 with AdN=C=S (Ad = 1-adamantyl) affords the insertion product {MeC(NAd)S}AlMe2 (1), which binds 1 equiv of AlMe3 to generate {MeC(NAd)S}AlMe2·AlMe3 (2). The alkane elimination reaction of AlMe3 and N,N′-disubstituted thiourea derivatives, (R′HN)2C=S, affords thioureido complexes {R′HNC(NR′)S}AlMe2 (3a, R′ = Ad; 3b, R′ = Ar = 2,6-iPr2-Ph). Carbodiimides, R′N=C=NR′, react with AlMe3 to afford acetamidinate compounds {MeC(NR′)2}AlMe2 (4a, R′ = Ad; 4b, R′ = Ar). Sequential addition of tBuLi and AlX2Cl (X = Cl, Me) to R′N=C=NR′ affords pivamidinate compounds {tBuC(NR′)2}AlCl2 (5b, R′ = Ar) and {tBuC(NR′)2}AlMe2 (6a, R′ = Ad; 6b, R′ = Ar). Complexes 1, 3a, 6a, and 6b have been characterized by X-ray crystallography.
