## Abstract The proton nuclear magnetic resonance spectra of benzo[__b__]โfuran, โthiophene and โselenophene oriented in a potassium laurate lyotropic liquid crystal have been analyzed. Geometrical information has been obtained and compared to previous thermotropic results and various hypothetical
## Abstract Intramolecular C๏ฃฟO bond forming reactions of aryl 2โbromobenzyl ketones lead to benzo[__b__]furans. The cyclizations can be catalyzed by 10โ mol% of iron trichloride (of 98% or of 99.995% purity) or subโmol% quantities of copper(II) chloride (of 99.995% purity).
