Organometallic Phosphazenes: Synthesis and Rearrangement of Propynyl and Propadienyl Cyclotriphosphazenes

摘要

Copper- or lithiophosphazene anions react with prop-2-ynyl bromide with the attachment fo the prop-2-ynyl group to the ring. Subsequent rearrangements yielded prop-1,2-dienyl or prop-1-ynyl derivatives. The mechanism of these reactions is discussed. These model reactions are of considerable significance for the analogous polymeric substitutions. (Author)
