The reaction of p-nitrobenzylidene dichloride with the lithium salt of 2-nitropropane gives initially the monosubstituted compound, p- NO2C6H4CH(Cl)CMe2NO2, by a radical-anion radical chain, SRN1 process. This compound then undergoes a radical-anion radical chain elimination reaction giving the styrene, p-NO2C6H4CH=CMe2, and the dimer of 2- nitropropane, Me2C(NO2)CMe2NO2. This latter reaction, which is designated ?ERC1?, also occurs in competition with an E2 reaction in the reaction of the methanesulphonate, p-NO2C6H4CH(OMs)CMe2NO2, with the 2- nitropropan-2-ide ion giving the above styrene and the enol methanesulphonate, p-NO2C6H4C(OMs)=CMe2, respectively. Catalytic, inhibition, and substituent effects are used to confirm the operation of these radical processes.

AbstractWe herein report that flow microreactors can promote an efficiency of radical chain reactions. The chain reactions with a fast propagation step can be accelerated by virtue of an efficient heat-transfer character of the microreactors, whereas the yield of those reactions with a slow propagation step was increased by flow microreactors. Moreover, the yield was further increased by a sequential addition of the initiators, which was allowed by a flow-sequential-addition system.
