Gao, Jie published the artcileCobalt complex bearing β-ketoamine ligand: syntheses, structure, catalytic behavior for styrene and methyl methacrylate polymerization, Category: pyrazoles-derivatives, the publication is Applied Organometallic Chemistry (2014), 28(8), 584-588, database is CAplus.
Cobalt complex based on β-ketoamine ligand [(Z)-4-((2,5-dimethylphenylamino) (phenyl)methylene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one] was successfully synthesized. The produced catalyst showed satisfactory activities in the cobalt-mediated radical polymerization of styrene and Me methacrylate with the common initiator of AIBN. The resulting polymerizations have the characteristics of living radical polymerization and displayed a nearly linear correlation between the number-average mol. weight and monomer conversion. Low polydispersity was obtained for all polymerizations, and the polydispersity index decreased with the increase of conversion. These improvements facilitate the implementation of styrene and methacrylate cobalt-mediated radical polymerization, and open the door to the scale-up of the process.
