Interaction of 2-Monosubstituted 1,3-Dioxolanes with Aluminacyclopentanes

Abstract

The interaction of 2-monosubstituted 1,3-dioxolanes with 3-hexyl-1-ethylaluminacyclopentane leads to the cleavage of the Al–C bond of the metallocycle and the formation of ethylene glycol monoethers after hydrolysis of the resulting reaction mixture. Catalytic amounts of ZrCl₄ or Ni(acac)₂ activate the process. The reaction of 2-monosubstituted 1,3-dioxolanes with 1-ethyl-3-naphthylaluminacyclopentane yields the product of cleavage of the exocyclic Al–Et bond of aluminacyclopentane.
