摘要

Both p-(trifluoromethoxy) valerophenone (l-OCF3) and p-(trifluorothiomethoxy)-y- methylvalerophenone (2-SCF3) were prepared by addition of the appropriate alkylmagnesium bromide to the aromatic nitrile. Figure 1 shows the phosphorescence spectra of both ketones at 77 K in hydrocarbon glasses. That of 1-OCF3 differs little from that of valerophenone itself (1-H), displaying the characteristic vibrational structure of n, r* ...
