Synthesis and Structure of a 1,3‐Diphosphacyclobutadienediide: An Aniomesolytic Fragmentation of a 1,3‐Diphosphetane‐2,4‐diyl in Solution

Abstract

Stepwise reduction of the 1,3-diphosphetane-2,4-diyl 1 by alkali metals (Li, K) leads to the 1,3-diphoshacyclobutadiendiide salts 2 by aniomesolytic fragmentation. DFT calculations provide insight into the reaction pathway.
