Unambiguous Assignments for the 1H-NMR Spectrum of Dibenzofuran and Structural Determination of New Isopropyldibenzofurans

Unambiguous Assignments for the 1H-NMR Spectrum of Dibenzofuran and Structural Determination of New Isopropyldibenzofurans

Assignments for the 1H-NMR spectrum of dibenzofuran were re-examined using a 400 MHz NMR spectrometer. Unambiguous assignments were obtained by both double resonance and 2-D NMR (C-H COSY) techniques. High resolution NMR spectra of six fractions through rectification of reaction mixtures of isopropy...

description Assignments for the 1H-NMR spectrum of dibenzofuran were re-examined using a 400 MHz NMR spectrometer. Unambiguous assignments were obtained by both double resonance and 2-D NMR (C-H COSY) techniques. High resolution NMR spectra of six fractions through rectification of reaction mixtures of isopropylation of dibenzofuran were recorded. Based on the unambiguous assignments for dibenzofuran, the structures of seven new isopropyldibenzofurans were determined.
