  • Polyoxometalate catalysts for the preparation of sterically hindered N-substituted aryloxyamines
    Patent number: 6841668
    Abstract: Sterically hindered N-substituted aryloxyamines are prepared by the Keggin polyoxometalate or the transition metal substituted polyoxometalate (TMS-POM) catalyzed decomposition of diazonium salts in the presence of a sterically hindered nitoxyl radical. These compounds are useful as thermal and light stabilizers for a variety of organic substrates.
