A high-yielding
and facile synthesis for diphosphane monochalcogenides
(<b>1</b><sub>Ch</sub><sup>(R)</sup>) and their constitutional
isomers, diphosphanylchalcoganes (<b>2</b><sub>Ch</sub><sup>(R)</sup>), was developed, featuring a condensation reaction between
chlorophosphanes (R<sub>2</sub>PCl) and sodium chalcogenides (Na<sub>2</sub>Ch, Ch = S, Se, (Te)). The optimized protocol selectively
yields either <b>1</b><sub>Ch</sub><sup>(R)</sup> (R<sub>2</sub>(Ch)PPR<sub>2</sub>) or <b>2</b><sub>Ch</sub><sup>(R)</sup> (Ch(PR<sub>2</sub>)<sub>2</sub>) depending upon the steric demand
of the substituents R. Reaction pathways consistent with the distinct
reaction outcomes are proposed. The application of <b>1</b><sub>Ch</sub><sup>(R)</sup> and <b>2</b><sub>Ch</sub><sup>(R)</sup> as an interesting class of ligands is exemplarily demonstrated by
the preparation of selected transition metal complexes.
