Group 10 phosphinite POCOP pincer complexes derived from 4-n-dodecylresorcinol: An alternative way to produce non-symmetric pincer compounds

摘要

Phosphinite POCOP pincer compounds 14-(n-C12H25)-C-6-H-3-1,3-(OPR2)(2)] R=Ph (1), Pr-i (2) derived from 4-n-dodecylresorcinol and their group 10 derivatives [MCI{3-(n-C12H25)-C6H2-2,6-(OPR2)(2)}] M(R) = Ni(Ph) (3), Ni(Pr-i) (6), Pd(Ph) (4), Pd(Pr-i) (7) and Pt(Ph) (5), Pt(Pr-i) (8) were synthesized and the catalytic activity of the palladium species explored in the Mizoroki-Heck and Suzuki-Miyaura cross coupling reactions.
