The procedure previously described for the preparation of 1-fluoro-2,2-di(4-nitrophenyl)ethane actually yields 1,1,2-tri(4-nitrophenyl)ethane.Fluoro-2,2-di(4-nitrophenyl)ethane has been prepared and rate constants, isotope effects, and activation parameters for the β-elimination reaction with methoxide ion in methanol are reported.These parameters indicate a concerted E2 mechanism, with a fairly symmetrical transition state.The subsequent dimerization reaction of the olefin product to yield 1,1,3,3-tetra(4-nitrophenyl)butene-1 is described.The reaction of 1,1,1-trifluoro-2,2-di(4-nitrophenyl)ethane with methoxide ion in methanol has been reinvestigated and the reaction on the first product 1,1-difluoro-2,2-di(4-nitrophenyl)ethylene with excess methoxide, to give di(4-nitrophenyl)ketene dimethylacetal in a multistep reaction, is reported.

The reaction between 2,2-di(4-nitrophenyl)-1,1,1-trifluoroethane and the alkoxide bases O-CH3, O-C2H5, O-nC4H9, O-CH(CH3)2 and O-C(CH3)3 in their corresponding alcohol solvents is a multistep reaction
