A variety of cyclopropenes undergo direct silylation using (trifluoromethyl)trimethylsilane in the presence of a copper–bisphosphine catalyst; under these conditions, cyclopropenes that might otherwise undergo ring-opening are silylated efficiently.
Two in One: A gold-catalyzed divergent ring-opening rearrangement of cyclopropenes has been developed for concise synthesis of structurally important polysubstituted naphthols and furans enabled by the dichotomous gold−carbenes. The use of different gold-catalysts allows for successful tuning of gold carbene reactivity or gold carbenoid reactivity in organic synthesis.
