Abstract

The reaction of a (2,4-di-tert-butyl-6-methylphenyl)dihalophosphine with magnesium leads to a tetraphosphacyclobutane, the dimer of the corresponding diphosphene (Ar-P=P-Ar). In dilute solutions the main product of this reaction is the diphosphine Ar-P(H)-P(H)-Ar in the form of diastereoisomers. By the31P CIDNP method the free-radical character of the reaction was established. The polarization coefficient and rate constant of the reaction were determined.
