Synthesis and structures of neutral and cationic 1-azaallylaluminium methyls†

Abstract

The 1-azaallylaluminium compounds [Al{N(R)C(Bu^t)C(H)R}{N(R)C(Bu^t)C(H)R}Me] (X-ray characterised), Al{N(R)C(Bu^t)C(H)R}Me₂, Al{N(R)C(Ph)C(H)R}Me₂ 3 and Al{N(R)C(Ph)C(H)R}₂Me(thf) were obtained from the appropriate methylaluminium chloride and 1-azaallyllithium; 3 with B(C₆F₅)₃ gave [Al{N(R)C(Ph)C(H)R}Me(thf)(OEt₂)][BMe(C₆F₅)₃] (R = SiMe₃).
