The Kulinkovich reaction 
The Kulinkovich reaction generates alcohol substituted versions of this chemical via the reaction of esters with titanium compounds and Grignard reagents. The insecticide pyrethrin contains this chemical as a core. Freund synthesized this molecule with an intramolecular Wurtz synthesis using sodium, which the similar Gustavson can synthesize this chemical with zinc. A zinc and copper couple delivers a carbenoid to create a stereospecific substituted example of this chemical in the (*) Simmons-Smith reaction. This chemical is no longer used for anesthesia. Coulson and Moffitt described its structure with three center bonds and Adolf von Baeyer explained its instability in terms of its high angle strain. This compound has bond angles equal to 60 degrees between its sp3 hybridized carbons. For 10 points, name this simplest cyclic alkane with only three carbons.
