Abstract
Disclosed are metal-bound tetracarbene catalysts, such as iron based aziridination catalyst, having the formula: wherein X is a group 6, 7, 8, 9, or 10 metal and wherein Z is a hydrogen, alkyl, aryl or organic group, wherein the alkyl, aryl or organic group is optionally are independently substituted. In a specific example, a metal-bound tetracarbene catalyst has the formula: Also disclosed are methods of making (synthesizing), transmetallation reagents, these agents, metal-bound tetracarbene catalysts, and a method of catalytic alkene aziridination, using the disclosed metal-bound tetracarbene catalysts.
Claims20
A compound having the formula:
- where X is a group 6, 7, 8, 9, or 10 metal, and wherein Z is a hydrogen, alkyl, aryl or organic group, wherein the alkyl, aryl or organic group is optionally and independently substituted at any or all positions.
A method of making a transmetallating agent, comprising:
- contacting a tetraimidazolium precursor (Me,EtTCPh)(X)4, where X is a counter ion, with a silver salt Ag(X), where X is a counter ion, in the presence of an organic solvent and optionally in the presence of a base, where the phenyl moieties can be independently substituted at any or all positions.
A transmetallating reagent, comprising [{(Me,EtTCPh)Ag}2Ag2](X)4, where X is a counter ion.
