[Question from NMRWiki Q&A forum] Chemical shift
Chemical shift
Hi there,I am seeing four signals at equal height between -0.6 and 0.5 PPM of a 1H NMR sample in dmso-d6. The reaction involves a reductive amination of a heterocylic aldehyde and a primary amine with NaCNBH3.Any thoughts.., appreciated.
