Abstract
Results Synthesis.---The triarylhaloethylenes l-Cl, 1-Br, and 3-Br were prepared by halogenation-dehydrohalogena-tion of the corresponding ethylenes without isolation of the ct., p-dihalides. 9'11, 14 The fluorenylidene derivative 4-Br was prepared similarly from the isolated a,@-dibromide. The dibromide 5-Br and the corresponding dichloride 5-C1 were prepared by adding the halogen to 9-anisylidenefluorenej but their analysis and nmr ...
