The reaction is best explained by an elimination-addition mechanism with 4-substituted cyclohexyne as a common intermediate. The cyclohexyne formation was confirmed by deuterium labeling and trapping to lead to [4 + 2] cycloadducts and a platinum-cyclohexyne complex. Cyclohexyne can also be ...
The effect of substituents on nucleophilic addition at the C=O bond, which occurs by the mechanism of intramolecular proton transfer, has been studied by the quantum-chemical MNDO/H method. The effect of nucleophiles and substituents at the carbonyl C atom in the gas phase is opposite to that...
