Abstract

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 residence time was extended to 63 s.
