Rh(III)-Catalyzed Olefination of <i>N</i>-Sulfonyl Imines: Synthesis of <i>Ortho</i>-Olefinated Benzaldehydes

Abstract

Rh(III)-catalyzed olefination of N-sulfonyl imines using acrylates and styrenes has been achieved for the synthesis of ortho-olefinated benaldehydes. This reaction proceeds via a chelation assisted C-H olefination/in situ hydrolysis process.
