Abstract:
The title compound, [Re(2)O(3)(C(19)H(20)N(2)O(2))(2)], is a hexacoordinate complex containing an [Re(2)O(3)](4+) core with a linear O=Re-O-Re=O bridge. The distorted octahedral coordination of the Re(V) atom is achieved by an N(2)O(2) donor set from the tetradentate imine-phenol ligand. The overall charge of the compound is neutral due to deprotonation of the phenol groups, and the terminating and bridging O atoms. The Re=O and Re-O bond distances of the [Re(2)O(3)](4+) core are 1.699 (4) and 1.911 (1) A, respectively. The Re-O and Re-N bond distances of the equatorial plane are in the ranges 2.024 (4)-2.013 (4) and 2.128 (5)-2.120 (5) A, respectively.

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...
