実験手順
The title compound was prepared from 1-(4-bromo-phenyl)-2,2-difluoro-ethanone (1.6 g) (for synthesis, e.g.: G. K. Prakash et al; Journal of Fluorine Chemistry; 112; 2001; p 357) by standard reduction with NaBH4 (0.515 g) in THF (20 ml) at RT and 2 h reaction time as colorless oil (1.23 g). MS (m/e)=236 [MH+].
