Diphenylcarbinyl derivatives. III. Solvolysis of polysubstituted benzhydryl chlorides. Examination of the Hammett relationship in a multiply-substituted system
The cooperative effect of Lewis pairs in the Friedel–Crafts hydroxyalkylation reaction: a simple and effective route for the synthesis of (±)-carbinoxamine
An efficient C–C bond formation strategy between aromatic/heteroaromatic π-nucleophiles and Lewis acid activated aldehydes is described. This aromatic electrophilic substitution reaction of arenes or heteroarenes is facilitated by Lewis acid AlBr3. Aromatic rings with electron donating substituents are excellent nucleophilic counterparts in this reaction, generating carbinols in excellent yields (61–94%)
Ligand design by‐pam: A ruthenium‐catalyzed asymmetric arylation of aldehydes with arylboronicacids has been developed, giving chiral diarylmethanols in good yields. The use of a chiral bidentate phosphoramidite ligand ((R,R)‐Me‐bipam) led to excellent enantioselectivities.
