摘要
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.
