Abstract The reaction of p-nitrobenzylidene dichloride with the lithium salt of 2-nitropropane gives initially the monosubstituted compound, p-NO 2 C 6 H 4 CH (Cl) CMe 2 NO 2, by a radical-anion radical chain, S RN 1 process. This compound then undergoes a radical-anion radical chain elimination reaction giving the styrene, p-NO 2 C 6 H 4 CH= CMe 2, and the dimer of 2-nitropropane, Me 2 C (NO 2) CMe 2 NO 2. This latter reaction, which is ...
