The reaction of 3-halo-4-aminopyridines with acyl chlorides and triethylamine is described. The pyridin-4-yl α-substituted acetamide products were obtained in moderate to high yields. The presented ...

Studies on the NMR methodology for characterizing the structure of polymers and biopolymers based on the understanding of the NMR chemical shift/structure correlation using solution-state and ...

We have investigated the scope and limitations of a method for predicting the regioisomer distribution in electrophilic aromatic substitution reactions that are under kinetic control. This method is ...
