Reactivities of a barrelene-type dialumane as an equivalent of an Al=Al doubly-bonded species

GRAPHICAL ABSTRACT

ABSTRACT

Barrelene-type dialumanes bearing bulky aryl substituents were synthesized, and their reactivity as synthetic equivalents of the corresponding dialumenes was elucidated. Reaction of the barrelene-type dialumanes with [Pt(PCy₃)₂] afforded platinum complexes of the corresponding alumylene (ArAl:). Structures of the newly obtained cyclic compounds containing an Al–Al bond and the platinum complexes were determined.
