Abstract: Process for the preparation of cyclic sulphates of general formula (I) by oxidation of a cyclic sulphite of general formula (II) by means of an alkali metal or alkaline-earth metal hypohalite and of a catalytic quantity of a ruthenium derivative (RuO2, RuCl3). In the general formulae (I) and (II), R1, R2, R3, R4, R5 and R6, which are identical or different, denote hydrogen, halogen, alkyl, alkoxy, aryl, aryloxy or alkoxycarbonyl.

Abstract: 1454587 6-Trichloroacetamido-penicillanic acid derivatives RHONE-POULENC SA 5 Sept 1974 [6 Sept 1973] 38881/74 Heading C2C The invention comprises compounds of the formula wherein R is an ester radical. They may be obtained by either oxidizing the S-atom of a compound of the formula to a sulphoxide group, with, e.g. H 2 O 2 , NaIO 4 or an organic per-acid; or reacting a compound of the formula wherein R 1 is PhCH 2 or PhOCH 2 , with or a derivative thereof. Compounds of Formula II may be obtained either by reacting a compound of the formula with Cl 3 CCOOH or a derivative thereof or by reacting an imino-chloride of the above compound with an alkali metal salt of Cl 3 CCOOH. Compounds of Formula III may be obtained either by oxidation of a compound of Formula IV or by esterification of a compound of the formula
