Abstract

2-Benzoyl-2-deuterio-5-phenyl-1, 3-oxathiole 3, 3-Dioxide (10-24. A mixture of 2-benzoyl-5- phenyl-l, 3-oxathiole 3, 3-dioxide (10, 0.5 g) in chloroformdl (3 ml), methanol-0-d (1 ml) and pyridine (0.1 g) was stirred at room temperature for 20 min. On addition of light petroleum the deuterated product 10-2-d crystallized: mp 139-140'; yield 0.4 g; Rf (benzene) 0.14; nmr (acetone-ds) 6 7.17 (s, 1,= CH), 7.5-8.0 (m, 10, aromatic); mass spectrum (70 eV) m/e (re1 ...
