Increasing the amount of the Et3N did not diminish the acyl fluoride formation (entry 4). Furthermore, the reaction displayed impressive speed, with optimal yields achieved even at reduced residence times in the second reactor of 90, 45, or as little as 36 seconds (entries 5-7). In the case of entry 4, the productivity of this process amounts to 0.792 g h -1 and the space-time yield to 149 g L -1 h -1 .
