The reaction between 2,2-diarylchromens and 1,1-diarylethylenes

Abstract

The product from the reaction of 2,2-diphenylchromen with a 1,1-diarylethylene has been shown by spectroscopic methods and by unambiguous synthesis to be a 2,2-diaryl-4-(2,2-diphenylvinyl)chroman. Similar reactions with related compounds have been carried out.
