Qw. Xing et al., SURFACE-COMPOUNDS OF TRANSITION-METALS .39. REDOX DEACTIVATION OF PHILLIPS CATALYSTS - FROM OLEFINS TO CYCLOPENTADIENYL COMPLEXES, Journal of molecular catalysis, 90(1-2), 1994, pp. 75-80
The blue compounds resulting from redox reactions of olefins with redu
ced Phillips catalysts were identified as CpCr(III) complexes of the f
ormula (Cp=CrCl2) 2 or Cp=CrCl2 . D in donor solvents, with Cp==alkyl
substituted eta5-cyclopentadienyl ring.
