Rd. Kohn et al., Triazacyclohexane complexes of chromium as highly active homogeneous modelsystems for the Phillips catalyst, CHEM COMMUN, (19), 2000, pp. 1927-1928
MAO activated 1,3,5-triazacyclohexane complexes of chromium(iii) are highly
active ethene polymerisation catalysts that resemble the Phillips catalyst
in many important properties and may represent the first good homogeneous
model system.
