Dialumenes are neutral Al-I compounds with Al=Al multiple bonds. A long and extreme trans-bent Al=Al bond with a low dissociation energy and bond order is reported in an amidophosphine-supported dialumene. In solution, the dialumene can dissociate into monomeric Al-I species, exhibiting reactivity through two modes of reaction: as dialumene or as aluminyl monomers.
Dialumenes are neutral Al-I compounds with Al=Al multiple bonds. We report the isolation of an amidophosphine-supported dialumene. Our X-ray crystallographic, spectroscopic, and computational DFT analyses reveal a long and extreme trans-bent Al=Al bond with a low dissociation energy and bond order. In solution, the dialumene can dissociate into monomeric Al-I species. Reactivity studies reveal two modes of reaction: as dialumene or as aluminyl monomers.
