Some 1,3-dihydro-1,3-dioxo-C't(substituted)- 2H-isoindole-2-acetate complexes of zirconium(IV): Synthesis and structural elucidation

Abstract

Some new complexes of composition (Pr<em>ⁱ</em>O)_4-nZr[OOCH(R)C- <img src='http://www.niscair.res.in/jinfo/equation44.gif' border=0>(O)]_n (where R = -H, -CH₃, -CH₂C₆H₅, -CH(CH₃)₂ -CH₂CH₂SCH₃, and -CHR- = -CH₂CH₂^-, n = 1 to 4) have been synthesized by the reaction of Zr(OPr<em>ⁱ</em>)₄Pr<em>ⁱ</em>OH with the corresponding ligands in different stoichiometric ratios in refluxing benzene medium. The structures of these complexes have been assigned on the basis of physicochemical and spectral (IR, ¹H & ¹³C NMR) studies.
