Two-step C–H, C–P bond activation at an α-diimine iron dinitrogen complex†
Abstract
Reduction of 6-coordinate (Ph2PPrDI)FeBr2 under N2 results in formation of the terminal dinitrogen complex, (Ph2PPrDI)FeN2. Heating this product to 75 °C allows for C–H and C–P activation of the chelate to generate the cisoid and transoid isomers of [(μ-PrPPh-κ5-P,N,N,Cγ,P-Ph2PPrDIPrPPh)Fe]2. Mechanistic possibilities for this transformation are discussed.
