Acetylated glycosyl-chromium(III)L (L=EDTA, NTA, IDA) complex intermediates ( 1 ) were detected in aqueous medium, with half-life times of 30–300 minutes. The decay of these intermediates led to glycals ( 7–9 ) of high purity in preparatively usa

A carbon carbon bond forming reaction has been developed by modifying the Nozaki–Hiyama reaction using a chromium(II)-aminopolycarboxylate complexes in a neutral aqueous medium at room temperature. Aldehydes and ketones can be coupled with aralkyl

Asymmetric reduction of acetophenone by Cr(II)/amino acid/water/DMF system is reported. Chemical yields up to 94%, enantiomeric excesses up to 74% were observed. The relevance to the Nozaki–Hiyama–Kishi reaction is discussed.
