A high-performance liquid chromatographic (HPLC) method is described for the quantitativedetermination of some aliphatic aldehydes and beta-hydroxyaldehydes as their 2,4-dinitrophenylhydrazone derivatives. A method is described for the preparation of derivatives for those beta-hydroxyaldehydes where no reference compounds of known purity are available. The detection limit of the method was 4.3-21
The reaction of the Schiff bases (obtained by condensing isatin with o‐aminophenol/o‐aminothiophenol/o‐aminobenzoic acid) with [RuX3(EPh3)3] (where X = Cl/Br; E = P/As) in benzene afforded new, air‐stable Ru(III) complexes of the general formula [Ru(L)X(EPh3)2] (L = dianion of tridentate Schiff bases). In all these reactions, the Schiff base ligand replaces one triphenylphosphine/triphenylarsine and

Transformation of acid chlorides into the corresponding aldehydes without over-reduction to alcohols was effectively achieved by the reduction of acyltributylphosphonium ions, formed in-situ from the chlorides and tributylphosphine in CH3CN, with ZnCu couple or Zn in the presence of CH3SO3H under an N2 atmosphere.
通过还原在CH 3 CN中由氯化物和三丁基膦就地形成的酰基三丁基phosph离子,通过ZnCu对或Zn在CH存在下的还原,可以有效地实现酰基氯转化为相应的醛而不过度还原为醇。3 SO 3的N在H 2气氛。
