Abstract

Substituted anilines react with phenylacetylene in the presence of montmorillonite KSF affording 1, 1-diarylethylenes 3 in good yields and excellent selectivities. In the presence of an excess of phenylacetylene, para-toluidine and para-anisidine give the corresponding 2, 6- bis (1-phenylvinyl) anilines.
