    • For the allylations catalyzed by 5a, 6b, and 7b at 0 °C, the product yield can be improved from 56% to 83% only in the case of 6b (X = O) although these catalysts were all still gradually consumed at this temperature. Apparently, the direct nucleophilic allylation of 6b was effectively slowed down at 0 °C
