Article abstract of DOI:10.1007/BF00810846

The basicities of 2H- and 4H-1,3-benzothiazines (1,2) were measured spectrophotometrically in buffer solutions.The rates of quaternization with methyl iodide were monitored in sealed ampoules by an oscillometric method.The stabilities were determined by m
