Abstract


In this work we used density functional theory (DFT) B3LYP/6-31G*(d) to study the stoichiometric reaction between the β-himachalene and dibromocarbene. We have shown that β-himachalene behaves as a nucleophile, while dibromocarbene behaves as an electrophile; that the chemical potential of dibromocarbene is superior to that of β-himachalene in absolute terms; and that β-himachalene reacts with an equivalent quantity of dibromocarbene to produce only one products P1: (1S,3R,8S) -2,2- dibromo -3,7,7,10

Author Keywords: [1+2] cycloaddition, B3LYP/6-31G*(d), charge transfer, chemospecificity, density functional theory (DFT), exothermic reaction, stereoselectivity, α-elimination.
