Synthesis and reactivity of bis-pentamethylcyclopentadienyl diiododialane (Cp*AlI)2: an aluminium(ii) precursor to (Cp*Al)4

Abstract

Use of an alternative aluminium(III) starting material has led to the isolation of a new aluminium(II) diiododialane, which functions as an intermediate in the synthesis of (Cp*Al)₄, reacts oxidatively with methyllithium, and undergoes oxidative cleavage of the Al–Al bond with an aryl azide.
