โœฆ Synopsis


FormaZdehyde dimethyl dithioaceta2 S,S-dioxide ii) reacted with an aZky2 bromide or a 2-aZkeny2 bromide C&J) under phase-transfer conditions using 50% aq. NaOH to give an aZkyZ or 2-alkenyl derivative of 2, whereas, in the reaction tith ,8 in the presence of K C03-KS in HMPA, z formed a I-alken-s-y1 derivative. Transformation of these products into t 8 e corresponding carboxylic esters was also described.

On irradiation (>290 rim) in the absence or presence of benzophenone, various aromatic aldehydes add to ketene dithioacetal S,S<lioxides to give the corresponding 1:1 adducts, which were shown to be synthetic precursors of indanone derivatives.
