In situ tracking and characterisation of scorpionate ligands via11B-NMR spectroscopy†
Abstract
Herein, we exemplify the use of 11B-NMR spectroscopy as a new means of tracking the synthesis of scorpionate ligands in situ and ascertaining their purity upon isolation. We have demonstrated the use of the characterisation technique on five well known scorpionate ligands as their potassium salts.
