ChemInform Abstract: Synthesis and Stereochemistry of 2‐Phenyl‐2‐oxo(thioxo,selenoxo)‐2‐phosphabicyclo(4.4.0)decan‐5‐ones.

Abstract

ChemInform Abstract The cyclohexenyl vinyl ketone (I) reacts with phenylphosphine (II) to give the phosphadecalone (III) which is converted to the oxo(thioxo,selenoxo) derivatives (IV). The compounds (III) and (IV) are formed as separable mixtures of conformers.
