Carbon-13 NMR Chemical Shifts of 1-Alkyl-3(5)-cyano-1H-pyrazole-4-carboxylic Acid Esters

A compilation of 13C NMR chemical shifts for 13 pairs of 3- and 5-cyano-substituted pyrazole regioisomers is reported.All of the ring carbon and cyano carbon 13C chemical shifts show a regular, predictable correlation with the particular isomer, whether 3-cyano or 5-cyano.These shifts occured in very narrow ranges, precluding any confusion of assignment within the group of compounds studied.X-ray crystallographic analysis was performed on one of the samples.
