Dirhodium tetraprolinate-catalyzed asymmetric cyclopropanations with high turnover numbers.
The bridged dirhodium tetraprolinate Rh(2)(S-biTISP)(2) (2) catalyzes the asymmetric cyclopropanation reaction between methyl phenyldiazoacetate and styrene at room temperature with high turnover number (92 000) and turnover frequency (4000 per h). [reaction: see text]
