Nizel’skii, Yu. N. published the artcileEffect of oligomeric glycol on the catalytic activity of copper β-diketone complexes during urethane formation, Synthetic Route of 14284-06-1, the publication is Ukrainskii Khimicheskii Zhurnal (Russian Edition) (1983), 49(5), 542-6, database is CAplus.
Kinetic data for urethane formation in isocyanate and diisocyanate systems with alkanol, glycol, and oligomeric glycol in the presence of CuL2 complexes (L = β-diketone) showed that catalyst reactivity depended on ligand structure and decreased in the order (of L): Me3CCOCH2COCMe3 > CH3COCH2CO2Et > PhCOCH2COCH3 > CH3COCH2COCH3 > CF3COCH2COCH3 > CF3COCH3COCF3. The effect of ligand structures on catalyst activity was weakened in systems containing an oligomeric glycol. This weakening of the ligand structure effect is discussed in terms of H bonding and the formation of intra- and intermol. complexes by oligomeric glycols.
