Synthesis, Characterization, Magnetic and Catalytic Properties of a Ladder‐Shaped Mn

Coordination Polymer
摘要:
Abstract[Mn(LH)(H2O)]n {1, where LH2– is the dianion of N‐(4‐carboxybenzyl)iminodiacetic acid} has been synthesized and its crystal structure has been determined. The crystal of 1 is built from 1D polymeric ladder‐shaped chains that extend to a 3D supramolecular architecture through H‐bonds. The compound was characterized with spectroscopic and physicochemical techniques. Variable‐temperature magnetic data suggest that there are weak antiferromagnetic interactions. Compound 1 has been evaluated as a heterogeneous oxidation catalyst. It catalyzes alkene epoxidation selectively in relatively high yields.

text] Electrophilic activation of hydrogen peroxide can be achieved in acidic alcohol solvents without the need for a metal catalyst. This concept is illustrated by the epoxidation of alkenes with H(2)O(2) employing phenol as a solvent. It is proposed that intermolecular hydrogenbonding between H(2)O(2) and phenol activates H(2)O(2) for oxygen-atom transfer. In this interaction, the role of phenol
