The PtCl2-catalyzed reactions between indoles and ethylpropiolate gave rise to mono and double addition products. The composition of the products was largely influenced by the substituents on the indoles as well as the amount of ethylpropiolate used. o-Alkynylanilines reacted with ethylpropiolate and dimethyl acetylenedicarboxylate under the catalysis of PtCl2 to generate the corresponding 2,3-disubstituted
