Abstract:
Bis(methylene)‐λ 4 ‐sulfane 1 , a 〉 C=S=C 〈 heterocumulene, was obtained as a red crystalline solid from the reaction between elemental sulfur and a carbenoid that contains sterically demanding silylalkyl groups. Under atmospheric conditions, and even at elevated temperatures, 1 exhibits extraordinary stability. The molecular structure and electron‐density distribution of 1 were analyzed by single‐crystal X‐ray diffraction analysis, which revealed a bent C=S=C geometry with C=S=C π‐bonds. These results, combined with those of variable‐temperature NMR measurements and theoretical calculations suggest a slow rotation of the S=C moieties in 1 , the stability and structure of which were further examined by theoretical calculations.
