Nitrogen-Ligated Iron Complexes: Photolytic Approach to the FeN(+) Moiety. Abstract Text:

The synthesis of (PNP)FeCl, (PNP)Fe[NH(xylyl)], and (PNP)FeN 3 are reported(PNP = ( (t)Bu 2PCH 2SiMe 2) 2N (-)). While the azide is thermally stable, it is photosensitive to lose N 2 and form [(PNPN)Fe] 2,in which the nitride ligand has formed a double bond to one phosphorus, and this N bridges to a second iron to form a 2-fold symmetric dimer. The reaction energy to form the (undetected) monomeric [eta (3)- (t)Bu 2PCH 2SiMe 2NSiMe 2CH 2P (t)Bu 2N]Fe is -15.9 kcal/mol, so this P (III) --> P (V) oxidation is favorable. The eta (2) version of this same species is less stable by 23.7 kcal/mol, which shows that the loss of one P--> Fe bond is caused by dimerization, and therefore, it does not precede and cause dimerization. A comparison is made to Ru analogs.
