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.

cyclopropenes, this methodology could be extended to a one‐pot synthesis of highly functionalized polycyclicaromaticcompounds (PACs). This transformation allows the synthesis of nitrile‐substituted alkenes and aromaticcompounds from rapidly accessed cyclopropenes using only commercially available reagents.
