This permits the designation regioselectivity to be used for partial regiospecificity. 2000 W. Cabri & R. Di Fabio From Bench to Market vi. 127 The regioselectivity of both couplings was not reported; however, in a similar reaction..a 2/1 ratio in favour of the useful isomer 20 was observed. < as lemmas |
