Ion-molecule Pairs in Solvolysis. Trapping of an Anthranyl Carbocation Molecule Pair by Solvent Water
Thibblin, Alf
, p. 697 - 699 (1990)
The specific acid-catalysed solvolysis of 9-benzylidene-10-methoxy-10-methyl-9,10-dihydroanthracene (1-OMe) in mixtures of water and acetonitrile proceeds mainly via a localized carbocation-molecule pair intermediate.
Hard-soft acid-base (HSAB) principle and difference in d-orbital configurations of metals explain the regioselectivity of nucleophilic attack to a carbinol in Friedel-Crafts reaction catalyzed by Lewis and protonic acids

The alkylations of aromatic compounds in presence of protonic acids yield two alkylated products arising from attack of a nucleophile (hard or soft) at two different carbocation (hard or soft) centers of a single compound. Hybrid density functional theory at B3LYP/6-31G* and B3LYP/6-31G levels and semiempirical calculations are employed to explain the observed trends in Friedel-Crafts reaction. Local HSAB principle based on local softness values explains the observed experimental reactivities.
