METHOD OF PRODUCING HYDROXYSTYRENE DERIVATIVE
-
Paragraph 0071, (2016/12/16)
PROBLEM TO BE SOLVED: To provide a method of producing hydroxystyrene compounds and their derivatives, simply in a high yield, by using relatively inexpensive and easily removable agents and relatively mild conditions. SOLUTION: A method of producing hydroxystyrene compounds comprises decarboxylating a hydroxycinnamic acid compound in a solvent containing at least one solvent having an amide bond in the presence of water and/or hydroxy-containing compound. A method of producing hydroxystyrene derivatives comprises reacting the hydroxystyrene compound with an acylating agent and/or a carbonic esterification agent. COPYRIGHT: (C)2015,JPOandINPIT
Process for preparing substituted styrenes
-
, (2008/06/13)
Substituted styrenes are synthesized by a simple, low temperature technique. A protected phenol styrene is reacted with an acid anhydride, dicarbonate, a halogen substituted alkyl, or an acid chloride in the presence of base to form a carbonyl substituted styrene. Unexpected yield decrease due to distillation is avoided because the product is sufficiently pure to be used without such distillation.
