Popis:	Xanthenyl and thioxanthenyl halides added readily to asymmetric diarylethylenes and their 2-halogeno-derivatives to give after dehydrohalogenation 1,1-diaryl-2-[xanthen(orthioxanthen)-9-yl]-ethylenes and 1,1-diaryl-2-halogeno-2-[xanthen(or thioxanthen)-9-yl]-ethylenes. The thioxanthenylethylenes were also obtained by another way. Reactions of these ethylenes with bromine, chlorine or sulfuryl chloride were influenced by the halogen and the nature of the p-substituent. Dehydrohalogenation of the 2-halogenoxanthenyl(or thioxanthenyl) ethylenes gave the corresponding 1,1-diaryl-2-[xanthen(or thioxanthen)-9-ylidene]-ethylenes.
