Regioselective Thiocarbonylation of Vinyl Arenes

Journal of the American Chemical Society, 2016
A palladium-catalyzed thiocarbonylation of styrene derivatives is reported for the first time. The combination of thiols as nucleophiles and a bidentate ligand ensures a unique reaction outcome with high regioselectivity toward the more valuable branched isomer and new reactivity.

Regioselectivity in Aromatic Claisen Rearrangements

The Journal of Organic Chemistry, 2003
Theoretical calculations and the isomeric product composition for a series of eight meta-substituted allyl aryl ethers confirm the reliability of a new (1)H NMR methodology used to predict aromatic Claisen regioselectivity from ground-state conformational preference of the reactant allyloxy group. Frontier HOMO-LUMO intramolecular orbital interactions,

Origin of the Regioselective Reduction of Chlorins

The Journal of Organic Chemistry, 2015
The reduction of a free-base chlorin generally forms a bacteriochlorin (BC), while the reduction of the corresponding metallochlorin forms a metalloisobacteriochlorin (M-iBC). This regioselectivity has been long known but was never fully rationalized.

Regioselectivity of the borylation of alkanes and arenes

Chemical Society Reviews, 2011
The borylation of alkanes and arenes has become some of the most practical C-H bond functionalization chemistry. Most striking is the high regioselectivity of these reactions. Rhodium and ruthenium complexes catalyze with exquisite selectivity the borylation of methyl C-H bonds over methylene or methine C-H bonds.
