The use of alkyl chlorides in Pd-catalyzed Mizoroki–Heck coupling reactions remains an unsolved problem despite their significant potential for synthetic utility and applicability. The combination of the high thermodynamic barrier of alkyl chloride activation and kinetic propensity of alkylpalladium complexes...
Pd-catalyzed reductive cross-coupling in the construction of Csp2−Csp3 bond. The Ullmann reaction, initially reported in 1901 [19], is one of the most efficient reductive cross-coupling in constructing C−C bonds between two aryl halides using stoichiometric copper. Ni(0)-catalyzed reductive...

摘要: The reaction is proposed to proceed via oxidative insertion of palladium into the aryl—halogen bond followed by complexation to the propargylic alcohol, two subsequent syn-palladations, and a final reductive elimination, generating one C—O and two C—C bonds in a single synthetic step....
The synthesis features the use of a Pd-ene reaction in the presence of CO to form the endocyclic alkene 8, a nonreductive acyl radical cyclization reaction, and a ring contraction reaction by the Wolff rearrangement. (+)-Acanthodoral has also been synthesized starting from (+)-S-2,2-...
Functionalized benzofurans, indoles, and phthalanes can be also synthesized by the tandem Ullmann–Goldberg cross-coupling and cyclopalladation-reductive elimination reactions, as well as by the related Pd-catalyzed processes involving hetero-Michael additions and cyclization in a one-pot process [50]...
