Abstract

original image

New carbones of the type Ph2E→C←SPh2(NMe) (E=S or Se) were synthesized and characterized. T. Fujii et al. show in their Communication on page 9569 ff. that the double protonation of Ph2Se→C←SPh2(NMe) gives a dication, whereas a C-metalated trication is obtained with silver(I). These reactions constitute the first experimental evidence for a carbodichalcogenurane behaving as a four-electron donor ligand.
