Abstract
The use of a buffered ionic liquid as a solvent for catalysts known to produce linear dimers from but-1-ene has been explored; this resulted in a significant enhancement of the activity of known catalysts, combined with the retention of both dimer selectivity and product linearity; in addition, the biphasic mode of operation allows easy catalyst recovery and recycle.
