Two tin(II) complexes, Sn(SPh)3- and Sn(C4H4O6)22-, besides NaHSO3, are involved in a procedure developed for the rapid transformation at pH 5-6 of R-CH2-NO2 into R-CHOH-SO3Na, from which the desired aldehydes have been isolated in 80-91% overall yields. Thus, a new alternative to the Nef traction is now in hand.
