1H/13C chemical shift correlations in the complex proton pattern of trans-TRIMEDLURE (cas 1009-74-1) isomers

Add time:07/18/2019    Source:sciencedirect.com

Proton/carbon-13 chemical correlations were determined for four trans-trimedlure isomers whose eight cyclohexyl protons, detected as a complex pattern in the region of 1.50–2.60 ppm, had not been previously assigned or correlated. The effects of axial and equatorial chloro substitution in the 4 or 5 position upon the chemical shifts of the eight cyclohexyl protons and their respective carbons are discussed.
