Abstract
On décrit la préparation de la phényl-2-phosphorine à partir du benzyl-1-phosphole par extension de cycle au chlorure de benzoyle, sulfuration et pyrolyse sur nickel vers 170–200°C. Dans le but de preparer des phosphorines acylées sur la position 4, on étudie la fonctionnalisation des sulfures de dihydro-1,6-phosphorines par métallation au butyllithium suivie d'une attaque des anions obtenus par divers electrophiles. Les essais de préparation des phophorines fonctionnelles correspondantes ont échoué. La dernière partie est consacrée à la préparation de phosphorines hétéroarylees à partir du phényl-1-diméthyl-3,4-phosphole et des chlorures de furoyle et de thénoyle. The synthesis of 2-phenylphosphorin from 1-benzylphosphole by reaction with benzoyl chloride, followed by sulfurization and pyrolysis with nickel powder at around 170–200°C is described. In order to prepare some unknown 4-acylphosphorins, we have also studied the metalation of 1,6-dihydrophosphorin sulfides. Our attempts have been unsuccessful. In the last part, we describe the synthesis of new 2-hetero-arylphosphorins from 1-phenyl-3,4-dimethylphosphole and furoyl and thenoyl chlorides.Keywords
