## Abstract Substitution reactions of 13 para‐ and meta‐substituted anilines with benzenesulfonyl chloride in varying mole fractions of benzene in propan‐2‐ol have been investigated conductometrically. The second‐order rate constants correlate well with pK~a~ values of anilines and with the Hammett
## Abstract The reaction kinetics of 2‐bromo‐5‐nitro thiophene with piperidine was studied in a solvent with a mixture of propan‐2‐ol with methanol and __n__‐hexane at 25°C. The measured rate coefficients of the reaction demonstrated dramatic variations in propan‐2‐ol–__n__‐hexane mixtures and mild
The magnitude of the a-effect for reactions of 4-nitrophenyl substituted benzoates with a pair of anionic nucleophiles is independent of the electronic nature of the acyl substituent, while the one for the corresponding reactions with a pair of neutral nucleophiles increases as the acyl substituent
## Abstract Various 4‐substituted benzo[__c__][2,7]naphthyridines were prepared from the corresponding 4‐chloro derivative by Pd(0) coupling reaction or nucleophilic substitution. More particularly, 4‐aroyl‐benzo[e][2,7]naph‐thyridines were synthesized by aroylation with arenecarbaldehydes in the p
