A regioselectivity switch in Pd-catalyzed hydroallylation of alkynes

By exploiting the reactivity of a vinyl-Pd species, we control the regioselectivity in hydroallylation of alkynes under Pd-hydride catalysis. A monophosphine ligand and carboxylic acid combination promotes 1,5-dienes through a pathway involving isomerization of alkynes to allenes. In contrast, a bisphosphine ligand and copper cocatalyst favor 1,4-dienes via a mechanism that involves transmetalation. Our study highlights how to access different isomers by diverting a common organometallic intermediate.

Palladium(0) versus nickel(0) catalysis in selective functional- grouptolerant sp3-sp3 carbon-carbon bond formations

We have uncovered Pd°-catalyzed intermolecular nonsymmetrical Suzuki-Miyaura-type sp3-sp3 C-C bond formations between allyl carbonates and nontoxic allyl, allenyl, or propargyl boronates. This report represents the first use of these

Mechanistic pathways in phosphate ester photochemistry

Initial bond breaking processes (homolysis vs heterolysis) of phosphate ester photosolvolysis were probed by chemically trapping the reactive intermediates with a tethered 5-hexenyl group. The resulting mechanistic picture is a blend of homolytic and heterolytic pathways, where the heterolytic cleavage is dominant.
