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.
两个锡(II)络合物,锡(SPH)3 -和Sn(C 4 H ^ 4 ö 6)2 2-,除了的NaHSO 3,参与的快速转化开发的过程在R-CH的pH值5-6将2 -NO 2转化为R-CHOH-SO 3 Na,从中分离出所需的醛,总产率为80-91%。因此,现在可以替代Nef牵引力了。
