A microreactor system consisting of membrane‐dispersion tube‐in‐tube microreactors and delay loops was developed for the continuous synthesis of 1‐ethoxy‐2,3‐difluoro‐4‐iodo‐benzene. Because of the high mass and heat transfer in the microreactor system, ortho‐ and halogen‐lithiation could be performed at −40 and −20°C, respectively, which are much higher than the temperature required (−70°C) for the...
Ethyl diazoacetate (EDA) synthesis using ethyl glycinate hydrochloride (EGH) and sodium nitrite (SN) as starting materials involves the diazo reaction (main reaction) and EDA decomposition reaction (side reaction). In this work, the main reaction is assumed to be faster than the side reaction; therefore, we determine the side reaction kinetics and the reaction heat of the side reaction and main reaction...
