Synthesis and structures of neutral and cationic 1-azaallylaluminium methyls†
Abstract
The 1-azaallylaluminium compounds [Al{N(R)C(But)C(H)R}{N(R)C(But)C(H)R}Me] (X-ray characterised), Al{N(R)C(But)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).
