4-addition is suppressed. The selectivity can be explained in terms of the HSAB theory: carbonyl groups require hard nucleophiles for 1,2-addition. The hardness...

choice of reactants is guided by a solubility chart or lattice energy. HSAB theory can also be used to predict the products of a metathesis reaction. Salt...

Acid Base (HSAB) theory, the bare hydron is an infinitely hard Lewis acid. The hydron plays a central role in Brønsted–Lowry acid–base theory: a species...
