英语翻译
For chromium,the early catalytic systems relyonligands
such as pyrrolides and carboxylates,while the more recent ones
are based on multidentate ligands displaying P,N,S,and O donors.
The array of successful chromium catalysts based on multidentate
ligands is diverse; they display donor combinations such as PP,
PNP,SNS,NNN,NNS,and NNO.Synthetic,structural,spectroscopic,
isotopic labeling and computational investigations have been performed
to address structure–activity relationships,the nature of
the active species,and details of the mechanism of catalysis.
