Title (EN) SYNTHESIS OF CYCLOPENTENONES WITH SULFONIC ACID REAGENTS
(FR) SYNTHÈSE DE CYCLOPENTÉNONES À L'AIDE DE RÉACTIFS D'ACIDE SULFONIQUE
Abstract:
(EN) A method comprising synthesizing a cyclic organic compound (3) via reaction of an unsubstituted or substituted alkene (1) with an unsubstituted or substituted acrylic acid (2) in the presence of a sulfonic acid reagent to make the cyclic organic compound (3) R1(H)C=C(H)R2 (1)
(FR) La présente invention concerne un procédé comprenant la synthèse d'un composé organique cyclique (3) par réaction d'un alcène (1) non substitué ou substitué avec un acide acrylique (2) non substitué ou substitué en présence d'un réactif d'acide sulfonique pour produire un composé organique cyclique (3) R1(H)C=C(H)R2 (1).
