The "C NMR spectra of 21 catechin derivatives substituted at C-6/C-S by bromine and/or hydrogen and at oxygen by methyl, acetyl and/or hydrogen have been analysed in deuteriated acetone and chloroform. When a methoxy group is flanked by two bulky orrho substituents (6-Br and C4), the M e 0 and ortho

## Abstract The carbon‐13 n.m.r. spectra of several oxaziridines were measured. Aliphatic and aromatic __ipso__ carbon atoms __trans__ to the lone pair of nitrogen in oxaziridines were shifted upfield by __c.__ 9 ppm, and 3.4 ppm, respectively, in comparison with isomers of inverted configuration.
## Abstract The carbon‐13 chemical shifts and coupling constants (__J__[^13^C^199^Hg]) have been determined for a series of eleven symmetrically substituted organomercurials. Empirical substituent parameters can be calculated which correlate observed and predicted chemical shifts for dialkylmercur
## Abstract The Ketonic ^13^C NMR signals of a series of 6‐hydroxy‐5‐oxobicyclo[2.2.2]oct‐7‐ene‐2‐carboxylic acid lactones and of haplophytine and related __N__‐substituted 3‐piperidinones occur at exceptionally high field; the structural factors which are responsible have been elucidated by compar
## Abstract Carbon‐13 chemical shifts of the cyclopropyl carbons of eleven 4‐substituted cyclopropylbenzenes have been measured under conditions effectively corresponding to infinite dilution in DCCI~3~. The substituent‐induced chemical shifts (SCS) of __both__ the α and β carbons of the cyclopropa
