The series of dinuclear to nonanuclear all-ortho methylene-bridged oligophenols 2 -9 has been synthesized according to a repetitive reaction sequence involving the C-ortho regiospecific condensation of appropriate phenoxymagnesium precursors with salicyl alcohol or paraformaldehyde. IR, UV, mass, 'H and I3C NMR characteristics of these oligomers are discussed. X-ray crystal structures of 2, 3, and 4 are also reported.
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.
