- Domino palladium-catalyzed heck-intermolecular direct arylation reactions
-
A domino palladium-catalyzed Heck-intermolecular direct arylation reaction has been developed, giving access to a variety of dihydrobenzofurans, indolines, and oxindoles. A variety of sulfur-containing heterocycles such as thiazoles, thiophenes, and benzo

- Reactivity of stable neopentyl-Pd intermediates in the absence of nucleophile
-
In the absence of any trapping agent, stable neopentyl-Pd intermediates can terminate a catalytic cycle by undergoing a regioselective C-H activation, leading to various spiro or fused cyclopropane derivatives in a straightforward manner. If the neopentyl

- Synthesis of heterocycles via ligand-free palladium catalyzed reductive Heck cyclization
-
Synthesis of five and six membered heterocycles, indolines, 2,3-dihydrobenzofurans, chromans, isochromans, 1,2,3,4-tetrahydroquinolines, and 1,2,3,4-tetrahydroisoquinolines, in 70-99% yield by a ligand-free palladium catalyzed reductive Heck cyclization of phenyl bromides and chlorides, under mild conditions, is reported. Water was found to be essential for these reactions.
