摘要: The concept of alkynophilicity is revisited with group 13 MX3 metal salts (M = In, Ga, Al, B; X Cl, OTf) using M06-2X/6-31+G(d,p) calculations. This study aims at answering why some these show reactivity toward enynes that similar to observed late-transition-metal complexes, notably Au(I) species, and them are inactive. For this purpose, the mechanism skeletal reorganization 1,6-enynes into 1-vinylcyclopentenes has been computed, including monomeric ("standard") dimeric (superelectrophilic) activation. Those results confronted deactivation pathways based on dissociation M-X bond. role ligand in stabilization intermediate nonclassical carbocation revealed, whole features required make a good π-Lewis acid discussed.
