Abstract

The synthesis of chiral polyoxometalates (POMs) has attracted increasing attention in recent years. The aim of this research was to construct different rigid POMs with organic derivatives. The POMs were synthesized with C–C or C–N links using N,N' -dicyclohexylcarbodiimide (DCC) protocol. The synthesized POMs are probably chiral because of increased steric hindrance of the bulky POMs to rotation at the C–N or C–C bond. Novel diorganoimido-substituted POM-based chiral macrocycles were synthesized using the DCC protocol. The POM macrocycles were produced in a controllable manner from achiral Lindqvist hexamolybdate and bis aryl amines bearing o-alkoxy chain substituents. Recent advances in synthesis of chiral POMs based on organoimido-substituted POMs are reviewed.
