Superbasic Anionic Calcium Alkyl Complexes: Templated Twofold Deprotonation of Benzene Open
Anionic calcium alkyl complexes have been synthesised through the reduction of ethylene by an anionic calcium hydride. The alkyl complexes are demonstrated to be superbasic, rapidly deprotonating ethers below room temperature, leading to C…
