G. Kickelbick et al., Extended X-ray absorption fine structure analysis of the bipyridine coppercomplexes in atom transfer radical polymerization, INORG CHEM, 40(1), 2001, pp. 6
The structure of the copper bpy catalyst in atom transfer radical polymeriz
ation was investigated in solutions of nonpolar solvents. It could be prove
d that the expected tetrahedral CUT structure is the predominant structure
in polymerization reactions. As counterions, different copper halides were
detected.
