synthesis for diphosphane monochalcogenides (1Ch(R)) and their constitutional isomers, diphosphanylchalcoganes (2Ch(R)), was developed, featuring a condensation reaction between chlorophosphanes (R2PCl) and sodium chalcogenides (Na2Ch, Ch = S, Se, (Te)). The optimized protocol selectively yields either 1Ch(R) (R2(Ch)PPR2) or 2Ch(R) (Ch(PR2)2) depending upon the steric demand of the substituents R. Reaction
Electron-transfer chemistry of (Me5C5)2Yb: cleavage of diorganoperoxide and related chalcogenides to give (Me5C5)2Yb(ER)(L) (E = O, S, Se, or Te; L = a Lewis base). Crystal structure of (Me5C5)2Yb(TePh)(NH3)
