Synthese d'α-Hydroxysulfinates
Mulliez, Michel,Naudy, Carole
, p. 2469 - 2476 (2007/10/02)
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.
SYNTHESIS OF SODIUM HYDROXYETHYLSULFINATE AND INVESTIGATION OF ITS REACTIVITY.
Makarov,Budanov,Shalimova
, p. 1004 - 1007 (2007/10/02)
The authors examine details of the preparation, and data on the reactivity of sodium hydroxyethylsulfinate (HES). As the result of studies of the dependence of the yield on concentration and temperature, and investigations of various methods of purification of the end product, the authors found the synthesis conditions for obtaining HES in fairly high yield (80%) and of at least 90% purity. Based on experimental data, it is shown that the mechanism of reducing action of various hydroxyalkysulfinates consists of successive stages of decomposition of the reducing agents with formation of HSO//2** minus or H//2SO//2 , and interaction of the latter with the dyes.
