Abstract

18 (68%) cessed at room temperature to minimize possible decompo-sition of 13; however, only benzyl chloride, 9, lO-dihydroanthracene (12, 43% isolated yield), and higher condensation products were detected. Similar results were obtained when 9 was formed in more dilute solutions of solvent. j3-(o-Bromopheny1) ethyl Bromide (14). Aryl halogenmetal exchange by reaction of 14 with n-butyllithium is se-lective at-100" C; the lithio derivative ...
