Asymmetric conjugate addition of cis-2-arylethenylboronic acids catalyzed by chiral diene/rhodium complexes: 1,4-rhodium shift from alkenylrhodium to arylrhodium intermediates

The reaction of (E)-1,2-diphenylethenylboronic acid 1 with 2-cyclohexenone in the presence of a chiral diene/rhodium catalyst (5 mol %) gave 3-[2-((E)-2-phenylethenyl)phenyl]cyclohexanone in 99% yield with 98.7% ee; the catalytic cycle involves a 1,4-rhodium shift from a 2-phenylethenylrhodium to an ortho-alkenylphenylrhodium intermediate. In the reaction of 1 with (E)-1-phenyl-2-buten-1-one, either the tandem 1,4-shift/arylation product or the direct alkenylation product is formed selectively by an appropriate choice of chiral diene ligand.

Preassociation, free-ion, and ion-pair pathways in the electrophilic bromination of substituted cis- and trans-stilbenes in protic solvents

Rates and products of electrophilic bromination of ring-substituted cis- and trans-stilbenes have been investigated in acetic acid, trifluoroethanol, ethanol, methanol, and water-methanol mixtures. The mY(Br) relationships (linear for nucleophilic solvent
