Abstract— –Irradiation of hexachlorophene in absolute ethanol yields a series of dechlorinated bisphenols resulting from loss of chlorine at the ortho and para positions relative to the hydroxy groups. The two primary photoproducts. 2.2′‐dihydroxy‐3,3′, 5,6,6′‐pentachlorodiphenylmethane and 2,2′‐dihydroxy‐3,5,5′, 6,6′‐pentachlorodiphenylmethane were identified by independent syntheses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
