Abstract

Abstract: The reaction of benzynes, generated from halobenzenes with lithium tetramethylpipiperide (LTMP) at –40 to –78 °C, with ketone enolates affords benzocyclobutenols in fair to good yields. ... Key words: benzyne, ketone enolates, anthracenes, benzocyclobutenol, alkoxides. ... Résumé : Les benzynes, obtenues à partir des halobenzènes avec le tétraméyhylpipéridure de lithium (LTMP) dans un intervalle de température de –40 à –78 °C, réagissent avec ...
