Coupling of Ph3SiNH2 with aryl halides by using Pd-PEPPSI-IPentCl {dichloro(3-chloropyridyl)[4,5-dichloro-1,3-bis(2,6-dipent-3-ylphenyl)imidazol-2-ylidene]palladium(II)} yields triphenylsilyl-protected anilines. These triphenylsilyl protected anilines can be isolated, alkylated without over...

Control experiments revealed that racemization is base-mediated, with no evidence of Pd-mediated 尾-hydride elimination when using Pd-PEPPSI-IPentCl, and that racemization occurs only after the product is formed, that is, the non-arylated starting amino ester does not deprotonate under our ...
The new catalyst described herein, Pd-PEPPSI-IPentCl-o-picoline, is able to aminate profoundly deactivated coupling partners when using only carbonate base at room temperature.doi:10.1002/ange.201310457Matthew PompeoDepartment of Chemistry, York University, 4700 Keele Street, Toronto, ON, M3J 1P3 ...
PEPPSIselectivityA single set of reaction conditions for the palladium-catalyzed amination of a wide variety of (hetero)aryl halides using primary alkyl amines has been developed. By combining the exceptionally high reactivity of the Pd-PEPPSI-IPentCl catalyst (PEPPSI=pyridine enhanced precatalyst ...
