✦ Synopsis
Application of 1,2-Bis(2-bromo-3,5-di-t-butylphenyl)ethane to the Preparation of Compounds Having Two Diphosphene Units.
-Reaction of the dibromide (I) with phenyllithium gives the homo-coupling product (II), which on lithiation with BuLi followed by addition of PCl3 affords the bis-dichlorophosphino compound (III). Final coupling of (III) with an arylphosphine (IV) leads to the E,E-diphosphene (V). -(YOSHIFUJI, M.;
