EFFICIENT SYNTHETIC METHODOLOGY FOR 1,3-DITHIOLANE-1-OXIDES via SINGLET OXIDATION OF 1,3-DITHIOLANES
Pandey, Bipin,Bai, Smita Y.,Khire, Uday R.,Rao, Ashok T.
, p. 3217 - 3218 (2007/10/02)
Singlet oxidation of 1,3-dithiolanes furnishes synthetically useful yields of 1,3-dithiolane 1-oxides.However, 2-ethyl-2-phenyl-1,3-dithiolane 13 gave 2-ethyl-4-hydroxy-2-phenyl-1,3-dithiolane 19 as a major product.
