Synthesis and structures of neutral and cationic 1-azaallylaluminium methyls

摘要

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}Me~2, Al{N(R)C(Ph)=C(H)R}Me~2 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(C_6F_5)_3 gave [Al{N(R)C(Ph)=C(H)R}Me(thf)(OEt_2)][BMe(C_6F_5_3](R = SiMe_3).
