A non-fluorous copper catalyst for the styrene cyclopropanation reaction in a fluorous medium.
The complex Tp(Br3)Cu(NCMe) (1), containing no fluorine atoms, can be dissolved in the perfluoropolyether FOMBLIN and employed as a catalyst for the styrene cyclopropanation reaction with ethyl diazoacetate, with activities and diastereo-selectivities identical to those observed under homogeneous conditions with the advantage of being able to use a fluorous separation technique for catalyst recycling.
