资源简介：
A new family of highly active ethylene tri-/tetramerization
catalysts
based on N-phosphinoamidinechromium complexes has
been investigated. The 1-hexene to 1-octene molar ratio can be tuned
from 140 to 1.5 by varying the steric environment around the chromium
center, and product purities are very good to excellent. Precatalyst
tridentate coordination effectively shuts down catalytic activity,
suggesting that THF abstraction from the chromium center by the Lewis
acidic aluminum activator is necessary to achieve an active catalyst
system.
