Abstract

PROCEDURE FOR THE OBTAINING OF ALCANOIC ACIDS REPLACED WITH AN AROMATIC GROUP IN THE ALPHA POSITION AND OF ITS ESTERS, IN FORMULA (I), IN WHICH AR IS AN AROMATIC GROUP; R1 IS HYDROGEN OR ALKYL OR AR AND R1, ARE PART OF A CONDENSED RING AND R2 IS HYDROGEN, ALCOHYL OR HYDROXIALCOHYL. IT CONSISTS IN THE REACTION OF HYDROLYSIS, OR TREATMENT WITH AN AGENT AFFINATED BY OXYGEN, OF ANALFA SULFONYLOXECETONE ACETAL OF FORMULA (II), IN WHICH R3 AND R4 ARE ALCOHYL OR TOGETHER A GROUP OF ALCOHYLENE; R5 IS ALCOHYL OR AROMATIC GROUP AND AR AND R1 ARE THE SAME AS IN FORMULA (I). HYDROLYSIS IS CARRIED OUT IN A POLAR SOLVENT IN A NEUTRAL OR BASIC MEDIUM AND AT A TEMPERATURE BETWEEN 0 AND 250C. TREATMENT WITH THE AGENT AFFINATED BY OXYGEN IS CARRIED OUT AT A TEMPERATURE BETWEEN 40 AND 150C. (Machine-translation by Google Translate, not legally binding)
