Improved synthesis and stability of 8-selenoquinoline and its sodium salt as organic reagents.
The synthesis of 8-selenoquinoline and its sodium salt has been improved by optimization of each process. The stability of the reagents in air and nitrogen has been examined and correlated with the drying method. Both 8-selenoquinoline and its sodium salt can exist as the monohydrate. It was found that the sodium salt of 8-selenoquinoline monohydrate is best as the weighing form of the reagent and that it can be kept stable under nitrogen in a vessel containing silica gel.
