Nucleophilic Substitution Reactions of Thiopheneethyl Arenesulfonafes with Anilines and N,N-Dimethylanilines
Nucleophilic substitution reactions of 2-thiopheneethyl benzenesulfonates (2-TEB) and 3-thiopheneethyl benzenesulfonates (3-TEB) with anilines and N,N-dimethylanilines (DMA) are investigated in acetonitrile at 60.0 C. The cross-interaction constants ρ XZ determined for the reactions with anilines are large negative (− 0.50) which are comparable to those for the similar predominantly frontside-a...

متن کاملNew fluoride-promoted hypoiodite-catalytic oxidative cycloetherification to aromatic spiroketals.
A new catalytic application of hypoiodite reagents generated in situ from iodide ions is found, which succeeded in the synthesis of bisbenzannelated spiroketal cores for the first time. Fluoride was proven to be obligatory for this spiroketalization, which is the first fluoride-promoted oxidative cycloetherification to aromatic spiroketals.
