文摘

The recently synthesized 3-tert-butyl-5-methyl-1,2,4-triazole reactedwith KBH₄ to give the new potassium tris(3-tert-butyl-5-methyl-1,2,4-triazolyl)borate K(Ttz^tBu,Me) ligand. Ttz^tBu,Me formed a four-coordinate (Ttz^tBu,Me)CoCl complex and five-coordinate(Ttz^tBu,Me)CoNO₃ and (Ttz^tBu,Me)ZnOAc complexes. When thesecomplexes were compared to their Tp^tBu,Me analogues, it was foundthat Ttz^tBu,Me resulted in negligible steric differences. K(Ttz^tBu,Me) ismore water-soluble than K(Tp^tBu,Me), so bulky tris(triazolyl)borateligands should lead to functional models for enzyme active sitesin an aqueous environment and the creation of water-solubleanalogues of Tp catalysts.
