## Abstract Proton chemical shifts, as well as solvent shifts induced by benzene, can be used for the structure determination of 4,5‐asymmetrically substituted 1‐(__N__‐isoimido)‐1,2,3‐triazoles, derived from the oxidation of α‐diketone bisaroylhydrazones. The geometry of the postulated ‘collision

## Abstract The aromatic ^1^H NMR shifts of __ortho__‐disubstituted benzenes were used to derive 285 pair‐induced chemical shifts (pairwise corrections) for vicinal pairs of the substituent set (F, Cl, Br, I, NH~2~, NHCOMe, NO~2~, OH, OMe, Me, CHO, COMe, CN, Ph). Using these parameters and a simple
Vacuum line kinetic studies of the reaction of p-toluenesulfonyl chloride and benzene or toluene, using aluminum chloride as the catalyst and dichloromethane as the solvent were determined at 25ЊC by means of gas chromatography. The reaction is first-order in arene, tosyl chloride, and in AlCl 3 as
