Question. List the symmetry elements of each of the following molecules (a) 1,2,3-trifluorobenzene, (b) 1,2,4-trifluorobenzene, (c) 1,3,5-trifluorobenzene, (d) 1,2,4,5-tetrafluoro-benzene, (e) hexafluorobenzene, (f) l,4-dibromo-2,5-difluorobenzene. [Pg.100]

Dibromo-5,6,7,8-tetrafluoroquinoxaline (187) gave 5,6,7,8-tetrafluoroqui-noxaline (186) [H2, Pd/CaCOs (deactivated. Lindlar s catalyst), EtsN CH2CI2, 3 days 44%] or 5,6,7,8-tetrafluoro-l,2,3,4-tetrahydroquinoxaline (188) (H2, Pd/C, EtsN, CH2CI2, 2.5 days >95%) note the selective dehalogenation in both procedures. ... [Pg.168]

When diphenylacetylene dissolved in cold chloroform reacts with iodine monofluoride suspended in trichlorofluoromethane, the iodine atoms in the primary addition product are easily replaced by fluorine to give l,1,2,2-tetrafluoro-1,2-diphenylethane (60%) along with benzil (10%). Since the C —Br bond is stronger than the C —I bond, the reaction of bromine monofluoride with diphenylacetylene gives 1,1-dibromo-2,2-difluoro-1,2-diphenylethane (65%) and benzil (15%). [Pg.235]
