In recent centuries, the traditional tank reaction provides a large number of chemical products thermolysis of azidoacrylates. However, potential safety hazard, environmental pollution, huge energy consumption, huge site area and scale-up difficulties are the shortcomings. Continuous flow micro-reactor, with its high efficient heat transfer and mass transfer, accurate temperature control, security and stability, no amplification effect and the advantages of real-time monitoring, can solve the problems which existing in the traditional reaction. This review focuses on new findings in continuous flow micro-reaction in the last five years. The nitration reaction, thermolysis of azidoacrylates, Grignard and Grignard-type reactions, coupled reaction, amination reaction, oxidation and reduction reaction, condensation reaction, cyclization reaction, multistep reaction in flow condition and the continuous flow micro-reactors are introduced. Meanwhile, the potential strengths of the continuous flow micro-reaction as well as the weaknesses are discussed.
