Sterically Encumbered Ligands in Coordination Chemistry

A bromo-functionalized 2,6-dimethylphenyl phosphate ligand (Dmpp-H2) (3) was synthesized by using a simple methodology and further the Dmpp-H2 was used in the synthesis of 4-bromo-2,6-dimethylphenoxy tert-butyl phosphonate ester (5) by reacting 3 with Tert-butyl phosphoryl chloride (1). The encumberedness of methyl and tert-butyl group provides solubility in the ligand systems. The all ligands were characterized analytical methods and further confirmed by spectroscopic methods.
