Be quick or take your time, depending on your goal: A microflow method for the generation and transformation of o‐, m‐, and p‐nitro‐substituted aryl lithium compounds enabled the selective use of either the kinetically or the thermodynamically preferred intermediate. In the example pictured, a residence time of 0.06 s at −48 °C led to the formation of 1, whereas 2 was obtained exclusively when the
