Studies on Thiocarbonyl Olefination Reactions with Phosphonium Ylides

Abstract

<jats:title>Abstract</jats:title><jats:p> Reactions of several semi-stabilized phosphonium ylides with 2,7-dibromofluorenethione and thiobenzophenone, have been reported to give substituted 9-benzylidene-2,7-dibromo-fluorenes and 1-(substituted phenyl)-2,2-diphenyl ethylenes respectively in fair to good yields. The structural identities were based on spectral data.</jats:p>
