Abstract
The invention comprises the compound SF5.CH2COOH and its preparation by oxidising SF5.CH2CHO (see Specification 941,392) under acid conditions, e.g. with KMnO4 in solution acidified with sulphuric acid, or with aqueous hydrogen peroxide. Examples prepare SF5.CH2COOH, its barium salt and the corresponding acyl chloride, the latter giving the acid on hydrolysis. The Provisional Specification refers generally to the production by the above method of compounds SF5 CR1R11. COOH, where R1 and R11 are hydrogen or alkyl, and specifies pentafluorosulphur propionic and isobutyric acids as products. The compound of the invention and, according to the Provisional Specification, its analogues also, is useful as a soil fumigant.
