The chemistry of novel chromium(IV) systems and fluorinated hypochlorites

Chromium(IV) has been of interest for some time because of its role as an intermediate in chromic oxidation reactions. Since there are not a great number of stable tetravalent chromium complexes known, and the use of such species as oxidizing agents has not been widely explored, the preparation, isolation and characterization of new stable tetravalent chromium species may allow chemists the opportunity to more fully understand the role which tetravalent chromium plays in oxidation reactions. The present study thus involves the synthesis of Cr(OC4H9)4 and other Cr(IV) derivatives and the use of Cr(OC4H9)4 in oxidative reactions with selected fluoridated alcohols. Interestingly, the reaction of fluoridated alcohols with Cr(OC4H9)4 or Cr(NEt2)3 was found to be a useful method for preparing products.
