Abstract

A cascade reaction of 2-N-unprotected-2-alkynylanilines and various electron-deficient alkenes in the presence of PdCl2 provided 2, 3-disubstituted indole derivatives, whereas, in the presence of Pd (OAc) 2, the same reaction resulted in the production of N-alkylated-2- alkynylaniline derivatives.
