New Stable 2,3-Dichloro,1,3-Diphosphapropenes; Synthesis And Characterization

Two novel diphosphapropenic compounds bearing two vicinal chlorine atoms on the P=C-P moiety have been obtained and completely characterized both through experimental (multinuclear NMR, HRMS, X-ray diffraction) and theoretical methods. These compounds are, due to their multiple coordination sites and the two halogen atoms, very interesting building blocks for new organometallic, cumulenic and coordination derivatives.
