Abstract

The N-imidoylamidine ligand i-Pr2C6H3N(C(Me)NC6H3i-Pr2)22 was prepared. Direct reactions with AlI3 or AlMe3 afforded [(i-Pr2C6H3N(C(Me)NC6H3i-Pr2)2)AlI2][AlI4] 3 and [i-Pr2C6H3N(C(Me)NC6H3i-Pr2)2)AlMe2][AlMe4]·AlMe34, respectively. Thermolysis of 4 gave (i-Pr2C6H3NC([double bond, length as m-dash]CH2)(NC6H3i-Pr2)(C(Me)NC6H3i-Pr2)AlMe26. Subsequent reaction with B(C6F5)3 gave the zwitterionic species [(i-Pr2C6H3)N(C([double bond, length as m-dash]CH2)NC6H3i-Pr2)(C(Me)NC6H3i-Pr2)AlMe(µ-MeB(C6F5)3)] 7. In a related reactions of 2, [Ph3C][B(C6F5)4] and AlMe3, AlH3·NEtMe2 or AlD3·NMe3, the complexes [(i-Pr2C6H3N(C(Me)NC6H3i-Pr2)2)AlR2][B(C6F5)4] (R = Me 5, H 8, D 9) and [(i-Pr2C6H3)N(C([double bond, length as m-dash]CH2)NC6H3i-Pr2)(C(Me)NC6H3i-Pr2)AlH][B(C6F5)4] 10 are formed. Single-crystal X-ray data for 2, 3, 5 and 10 are reported.
