Synthese d'α-Hydroxysulfinates

α-hydroxysulfinates 1 (table 1) are synthesized (path b, Fig. 1), by slowly adding aldehydes 3 to the mixture sodium dithionite 4 - sodium hydroxide.Owing to their limited stability the products 1 are readily separated from sodium sulfite 5 and isolated.They are easily distinguished (table 2) from their oxydation counterparts 2.
