The most preferable stereoisomers in series of vicinally substituted P-phenyl-4-phosphorinanones and phosphabicyclodecan-5-ones are those with an equatorial orientation of the phenyl group attached to the phosphorus atom.The conformational free energies of the methyl and phenyl substituents in these compounds are greater than in cyclohexane derivatives.
