Fl. Atkinson et al., ARENEDIAZONIUM ION INSERTION INTO AN IRON PHOSPHINE BOND - SYNTHESIS AND CRYSTAL-STRUCTURE OF [FE(NO)2(PPH2CH2CH2P(PH)2NN(C6H4F-P))][PF6].OC4H8, Journal of the Chemical Society. Dalton transactions, (7), 1994, pp. 1161-1162
The reaction of [Fe(NO)2(dppe)] (dppe = Ph2PCH2CH2PPh2) with [N2C6H4F-
p][PF6] gave [Fe(NO)2{PPh2CH2CH2P(Ph)2NN(C6H4F-p)}][PF6] X-ray studies
on which revealed the formation of a novel chelating ligand bound to
iron through phosphine and eta2-N=N functionalities and resulting from
insertion of an arenediazo group into an iron-phosphorus bond.
