## ABSTRACT Enantioselective syntheses of two stereoisomers of 3‐hydroxy‐4‐phenyl‐2‐butanone were investigated via Shi's asymmetric epoxidation or Sharpless asymmetric dihydroxylation of silyl enol ether. (__R__)‐3‐Hydroxy‐4‐phenyl‐2‐butanone was obtained in 73% enantiomeric excess (__ee__) by Shi'
A new extraction-spectrophotometric method for the determination of cadmium, basedon the formation of the complex Cd(I1): 2-(5'-ethyl-l',3',4'-thiadiazolyl--2'-azo)-4-rnethoxyphenol into benzene is developed ( E = 37,800 l.mol-1.cm-l at 6 1 0 nm).
