実験手順

In a reaction conducted in an analogous manner to Example 4, the reagent from Example 2 converted benzophenone into 1,1-diphenyl-1-heptene in a 71% yield. This product could easily be separated from reduction products by column chromatography on silica gel using hexane as the eluent, or even by simple distillation. This hydrocarbon was identified by spectral comparison with an authentic sample that was obtained by the partial reduction of known 1,1-diphenyl-1,6-heptadiene (J. J. Eisch et al., J. Am. Chem. Soc., 1979, 101: 1148).
