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.
Direct allylation of benzyl alcohols, diarylmethanols, and triarylmethanols mediated by XtalFluor-E

We report the direct allylation of benzyl alcohols, diarylmethanols and triarylmethanols mediated by XtalFluor-E using allyltrimethylsilane. The resulting allylated products are obtained in moderate to high yield.
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.
Enantioselective Addition of Aryl Groups to Aromatic Aldehydes Using Chiral Aryltitanium Binaphthol Derivatives
Seebach, Dieter,Beck, Albert K.,Roggo, Silvio,Wonnacott, Anne
, p. 3673 - 3682 (2007/10/02)
Chiral, non-racemic organotitanium reagents are generated in situ from binaphthol, chlorotriisopropoxytitanium and aryl Grignard reagents in tetrahydrofuran (THF).These reagents transfer aryl groups to aromatic aldehydes with high enantioselectivity .By this method, enantiomerically pure benzhydrols are available (3-13, Table 1).In the cases, in which the absolute configuration of the products is known, the reaction occurs with relative topicity lk.
