Tandem Diazotization Heck Reactions: A General Synthesis of Substituted Styrenes from Anilines

Article abstract of DOI:10.1016/S0040-4039(00)78494-2

The palladium-catalyzed olefination of different anilines with ethylene is shown to proceed generally in good yields.The substituted styrenes were obtained highly selective in a direct tandem diazotization Heck reaction at room temperature under atmospheric pressure of ethylene without concomitant side reaction to stilbenes.
