Abstract
The high-resolution proton magnetic resonance spectrum of 2-carbomethoxy 5,6-dimethyl bezofuran has been obtained at 56·4 Mc/s. This N.M.R. (nuclear magnetic resonance) spectrum is complex since there are observable spin-spin coupled interactions between all the ring protons, between the protons of the 5 and 6 methyl groups and between the 4 and 7 protons and the protons of the 5 and 6 methyl groups. By taking advantage of solvent shifts and employing frequency-sweep spin decoupling techniques it was found thatKeywords
