Abstract

Studies of the kinetic isotope effects and the influence of acidity in substitution and coupling reactions of thiophene involving Pd(II) indicate that both reactions proceed through a common intermediate 2-C4H3S−Pd(II). Its interaction with Pd(II) leads to hydroxylation of thiophene to form coupling reaction products.

Abstract

Изучены кинетические изотопные эффекты и влияние кислотности среды в реакциях замещения и сочетания тиофена при участии Pd(II). Заключено, что обе реакции протекают через общий интермедиат 2-ткенил-палладий(II), взаимодействие которого с палладием(II) ведёт к гидроксилированию тиофена, а с тиофеном-к продуктам сочетания.
