The recently synthesized 3-tert-butyl-5-methyl-1, 2, 4-triazole reacted with KBH4 to give the
new potassium tris (3-tert-butyl-5-methyl-1, 2, 4-triazolyl) borate K (Ttz t Bu, Me) ligand. Ttz t
Bu, Me formed a four-coordinate (Ttz t Bu, Me) CoCl complex and five-coordinate (Ttz t Bu,
Me) CoNO3 and (Ttz t Bu, Me) ZnOAc complexes. When these complexes were compared to
their Tp t Bu, Me analogues, it was found that Ttz t Bu, Me resulted in negligible steric
differences. K (Ttz t Bu, Me) is more water-soluble than K (Tp t Bu, Me), so bulky tris …

The recently synthesized 3-tert-butyl-5-methyl-1,2,4-triazole reacted with KBH4 to give the new potassium tris(3-tert-butyl-5-methyl-1,2,4-triazolyl)borate K(TtztBu,Me) ligand. TtztBu,Me formed a four-coordinate (TtztBu,Me)CoCl complex and five-coordinate (TtztBu,Me)CoNO3 and (TtztBu,Me)ZnOAc complexes. When these complexes were compared to their TptBu,Me analogues, it was found that TtztBu,Me resulted in negligible steric differences. K(TtztBu,Me) is more water-soluble than K(TptBu,Me), so bulky tris(triazolyl)borate ligands should lead to functional models for enzyme active sites in an aqueous environment and the creation of water-soluble analogues of Tp catalysts.
