Abstract
[76089-77-5] C3CeF9O9S3 (MW 587.33) InChI = 1S/3CHF3O3S.Ce/c3*2-1(3,4)8(5,6)7;/h3*(H,5,6,7);/q;;;+3/p-3 InChIKey = PHSMPGGNMIPKTH-UHFFFAOYSA-K (water-tolerant, mild Lewis acid capable of promoting acetal hydrolysis,2 cleavage of p-methoxybenzyl ethers,3 acetylation of alcohols and sugars,4, 5 acetalization;6-8 catalyzes addition of homoallyl alcohols to aldehydes;9 catalysis of Friedel–Crafts acylations10) Alternate Name: cerium(III) triflate. Physical Data: mp >300 °C. Solubility: sol methanol and water. Form Supplied in: white powder, commercially available. Preparative Method: most conveniently prepared from cerium(III) chloride and trifluoromethanesulfonic acid in water.1 Handling, Storage, and Precautions: hygroscopic; can be handled in air with quick transfers; pure samples are only mildly corrosive. Appears to be indefinitely stable in the absence of air, moisture, and light. When not in use, tightly seal the container and store in a dry, cool place.
