Abstract |
We have developed a Pd-catalyzed tandem reaction with terminal alkynes and nitropyrazoles. Although terminal alkynes have been considered to be challenging to use in C-H activation of (hetero)arenes because of facile dimerization, we achieved the tandem reaction forming the Pd-alkenyl complex to generate enynyl pyrazoles using diynes as a counterpart of pyrazoles. Depending on the equivalent of terminal alkynes and the type of oxidants, either the hydroarylation or the direct alkynylation occurred through different catalytic cycles. |
