Our previous work showed that one of three equivalent pyrazole rings of the scorpionate KTp* can be replaced with a benzotriazole ring. The goal of this study is to determine the generality of the metathesis method for the synthesis of boron-centered heteroscorpionate ligands. The variables being investigated include the counterion (K+ vs. Li+), solvent (DMF vs. toluene), and incoming aromatic ring (benzotriazole vs. 1,2,3-triazole, 1,2,4-triazole and 2-mercapto-1-methylimidazole). When the incoming ring is 1,2,3-triazole, the resultant LiTp'' ligand forms cis and trans isomers of the form L2Ni, where L = Tp'', when reacted with NiSO4. Analogous studies, which use different incoming heterocycles, and in which the L2Cu complexes were synthesized, will also be reported.
