2-methoxy-5-bromophenyl antimony compounds. Synthesis and structure
摘要:
Reaction of 2-methoxy-5-bromophenyllithium with antimony trichloride in diethyl ether affords tris-(2-methoxy-5-bromophenyl)antimony benzene solvate I. Its structure and chemical transformations into the new antimony aryl derivatives were studied.

various organolithium reagents to form porphyrins with exocyclic double bonds. The reaction involved conversion with LiR to the respective alcohol. Subsequence dehydratization of the alcohols yielded olefinic systems in which the double bond formed was located in the meso substituent neighboring the β position, i.e., the result of a 1,5-hydride shift. Depending on the organolithium reagent used various olefinic

Lithiumverbindungen von Phenoläthern reagieren mit α‐halogenierten Aminen zu Dialkylaminomethyl‐phenoläthern. Auf diesem Wege sind auch Aminomethylierungsprodukte zugänglich, die durch direkte Umsetzung der Phenoläther mit α‐halogenierten Aminen nicht zu erhalten waren.
