An NHC‐Coordinated Silicon/Sulfur Analogue of an Acyl Carbene
Angewandte Chemie, EarlyView.An NHC complex of an Si/S analogue of an acyl carbene is synthesized by the reaction of a disilyne with a cyclic thiourea. The observed Si2S three‐membered ring with unsymmetrical Si─S distances and a Si─Si single bond is consistent with intramolecular coordination of the silathioacyl sulfur to the silylene center.

Angewandte Chemie, EarlyView.Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.
