ChemInform Abstract: Preparation and Reaction of γ‐Ethoxy and (Phenylthio)allenylstannanes.

Abstract

ChemInform Abstract The alkynes (I) are coupled with the tributylstannylmethyl compounds (II) to give the stannylallenes (III). The phenylthioallenyl derivatives (IIId) react with the acetals (IV) in the presence of TiCl4 to yield the phenylthioalkynyl ethers (V).
