✦ Synopsis

A13C NMR study of twenty-one 4.4dimethyl-2-phenyl-l.3-oxazolines has shown that the chemical shifts of the oxazoline moiety are insensitive towards substitution on the phenyl ring.

## Abstract The ^13^C NMR spectra of a series of 2‐X‐4‐Y‐5‐Z‐substituted 2H‐pyridazin‐3‐ones were measured and assigned on the basis of results from one‐dimensional semi‐selective INEPT or one‐dimensional relayed coherence transfer (HICUUP) experiments.

## Abstract A compilation of ^13^C NMR chemical shifts for 13 pairs of 3‐ and 5‐cyano‐substituted pyrazole regioisomers is reported. All of the ring carbon and cyano carbon ^13^C chemical shifts show a regular, predictable correlation with the particular isomer, whether 3‐cyano or 5‐cyano. These sh

Carbon-13 chemical shifts of eight 3H-1,4-benzodiazepine-2,5( lH, 4H)-diones are reported. The carbonyl chemical shifts have diagnostic value for distinguishing these diones from the isomeric 1,3-benzodiazepine-2,5-dione structures.
