Stabilization and Reactivity of the Lewis Acidic Solvated Phenylcalcium Cation

摘要

Calcium, the fifth most frequent element on earth, is the ideal metal for stoichiometric and catalytic applications owing to its non-toxicity, global abundance, and low cost. Furthermore, this alkaline-earth metal shows favorable chemical properties in its compounds, combining the beneficial behavior of the alkali metals (highly heteropolar bonds, high nucleophilicity of the counteranions) and Group 3 elements (d orbital participation, Lewis acidic character of the cation, catalytic activity) as well as Group 13 metals (highly Lewis acidic nature).
