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
Bis‐phosphanated compounds are regarded as the most ubiquitous privileged ligand structures in transition‐metal catalysis. The development of highly atom economical reactions is of great importance for their syntheses because less atom economical methods often require complicated purification procedures under inert atmospheres to remove excess starting materials and byproducts. Herein, the photoinduced
