Title (EN) SYNTHESIS AND PREPAPRATION OF 2, 3-DIBROMO-2-PROPEN-1-OL
(FR) SYNTHÈSE ET PRÉPARATION DE 2,3-DIBROMO-2-PROPÈN-1-OL
Abstract:
(EN) The disclosure describes methods for preparing 2,3-dibromo-2-propen-l-ol, or dibromoallyl alcohol, and isomerically enriched compositions of the same. The process can include reacting propargyl alcohol with elemental bromine to produce the di-bromo product. High yields of the dibromoallyl alcohol can be achieved, with E-isomer content of greater than 95%.
(FR) L'invention concerne des procédés de préparation de 2,3-dibromo-2-propèn-l-ol, ou d'alcool dibromoallyle, et des compositions enrichies en isomère de ceux-ci. Le procédé peut comprendre la réaction d'alcool propargylique avec du brome élémentaire pour produire un produit di-bromo. Selon l'invention, des rendements élevés d'alcool dibromoallyle peuvent être obtenus, avec une teneur en isomère E supérieure à 95 %.
