Webacid mixtures for which the methinyl I3c peaks were found unsuitable. Based on evidence (2) that the chemical shifts of the 13c0 signals increase in sequence with the position of the bromine atom, the values represented by Fig. 1B amount to a ratio of 1: 1.5: 1.8:2.6:2.7, i.e., in good agreement with that esti- mated for the methinyl carbons.
