Abstract: Abstract Pd-catalyzed hydroarylation reactions of ynamides were studied in pure water in the presence of the water-soluble industrial TPPTS ligand in comparison with the use of PCy3 or P(o-Tol)3. Pd(OAc)2/TPPTS (3,3′,3″-phosphanetriyltris(benzenesulfonic acid) trisodium salt) system… read more here.

DOI: 10.1021/acs.orglett.0c03395
Abstract: The mechanism of nickel-catalyzed hydroarylation of styrenes has been explored with density functional theory. Instead of the stepwise pathway via a Ni(II)-H species, computational results unveil that the concerted RO-H oxidative addition/olefin insertion takes place… read more here.

DOI: 10.1021/acs.orglett.9b01645
Abstract: A facile regioselective switch for nickel-catalyzed hydroarylation of vinylarenes with benzothiazoles has been developed, which relies on the simple structural variation of novel Ni(II) complexes of the type Ni(NHC)[P(OR)3]Br2. Using magnesium turnings as the reductant,… read more here.

DOI: 10.1039/d1cc07309e
Abstract: A simple Ni(II)-catalyzed C-H hydroarylation of diarylacetylenes with imidazolium salts without adding any ligand was developed. It provides a facile and efficient access to (E)-2-(1,2-diarylvinyl)imidazolium salts. The preliminary results indicate a rare nonredox catalytic cycle… read more here.

DOI: 10.1055/s-0039-1690758
Abstract: A simple synthetic procedure for the Pd-catalyzed hydroarylation of diazoacetic ester has been previously developed in our laboratory. Now we have applied this methodology for hydroarylation of α-diazocarboxylates/α-diazophosphonates. Diazo compounds reacted with aryl iodides and… read more here.
