Pyrethrin contains one of these molecules bridging an ester and an alkene moiety, and 1-1-1-propellene contains three of these molecules fused together. DBU and a diethyl malonate derivative are used to add this moeity to a fullerene in the Bingel reaction, and its bonds have partial pi character according to the Walsh orbital model. Adding a carbene to an alkene is another way of generating it; that same transformation can be performed via the Simmons-Smith reaction. Bent or banana bonding is used to explain how it relieves its incredible ring strain, which occurs due to the sixty degree angles between its carbon-carbon bonds. For 10 points, name this compound consisting of three carbons in a ring.
