摘要： An amine ether of formula (A) wherein a is 1 or 2; and when a is 1, E is E'; when a is 2, E is L; E' is C1-C36 alkyl; C3-C18 alkenyl; C2-C18 alkinyl; C5-C18 cycloalkyl; C5-C18 cycloalkenyl; a radical of a saturated or unsaturated aliphatic bicyclic or tricyclic hydrocarbon of 7 to 12 carbon atoms; C2-C7alkyl or C3-C7alkenyl substituted by halogen; C7-C15aralkyl or C7-C15 aralkyl substituted by C1-C4 alkyl or phenyl; or E' is a radical of formula (VII) as explained in claim 1; T' is tertiary C4-C18alkyl or phenyl, each of which are unsubstituted or substituted by halogen, OH, COOR21 or C(O)-R22; or T' is C5-C12cycloalkyl; C5-C12cacloalkyl which is interrupted by at least one O or -NR18-; a polycyclic alkyl radical having 7-18 carbon atoms, or the same radical which is interrupted by at least one O or -NR18-; or T' is -C(G1)(G2)-T''; or C1-C18alkyl or C5-C12cycloalkyl substituted by F(I)T'' is hydrogen, halogen, NO2, cyano, or is a monovalent organic radical comprising 1-50 carbon atoms; or T'' and T' together form a divalent organic linking group completing, together with the hindered amine nitrogen atom and the quaternary carbon atom substituted by G1 and G2, an optionally substituted five- or six-membered ring structure; and all other residues are as defined in claim 1, are obtained in good yield from the corresponding N-oxyl hindered amine precursor by reaction with a hydrocarbon E1-H or H-L-H in the presence of an organic hydroperoxide and a catalytic amount of copper or a copper compound. The products of present process find utility as polymerization regulators and/or light stabilizers for organic material.
