FRAGMENTATION OF 1,3-DITHIOLANE-DERIVED SULFUR YLIDES. A CONVENIENT THIOALDEHYDE SYNTHESIS

S-Ylides 10, which are generated by regiospecific deprotonation of 1,3-dithiolanium salts 9 with electron-withdrawing groups in the 4,5 positions, fragment under mild conditions to generate thioaldehydes 12.

ANIONIC -CYCLOADDITION OF DITHIOBENZOATE ION AT ACTIVATED MULTIPLE BONDS

The dithiobenzoate anion (in the form of the triethylammonium salt) reacts with activated acetylenes by a mechanism of anionic -cycloaddition with the formation of 3-phenyl-1,3-dithioles.With an activated alkene (dimethyl fumarate) the acyclic product from Michael addition of dithiobenzoic acid at the double bond is formed in addition to the corresponding 1,3-dithioles.
