Abstract:
The extended 1D tungstophosphite molecular wire is obtained by connection of polyoxometalates. Self-assembly of a triangular PIII O3 unit with tungstate produces a hexagonal [HPIII W6 O21 ]2- building block, which then connects linearly to form the molecular wire. The surface property of the molecular wire is tuned to hydrophobic using organoammonium cations, and the surface-modified material disperses easily in organic media. The multifunctional material, which possesses nanostructure, hydrophobicity, and redox properties simultaneously, is suitable for olefin epoxidation in organic solvent.

Acid-Catalyzed Ring-Opening of Epoxides
Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
