| —— | N,N'-(1,1,2,2-tetraphenyl-1l5,2l5-diphosphane-1,2-diylidene)bis(P,P-diphenylphosphinoselenoic amide) | 182755-18-6 | C48H40N2P4Se2 | 926.674 |
The reaction of Ph2P-N=PPh2-PPh2=N-PPh2 (Ph = C6H5, 2) with [CpFe(CO)(μ-CO)]2 (Cp = C5H5, 3) yields under elimination of a PPh2-group from 2 and cleavage of the Fe-Fe bond in 3 the monocyclic ferraphosphazene complex Cp(OC)
While the reaction of anhydrous iron(III) chloride with the chelate ligand [(C6H5)2P(O)]2NH (6) is an efficient way to synthesize the new tricyclic compound imido-tetraphenyl-diphosphinato-O,O′iron(III), [FeO-P(Ph2)=N-P(Ph2)=O}3] (4), treatment of [(C6H5)2P]2NLi (1) with anhydrous iron(III) fluoride in THF represents a simple route to obtain the phosphorus-phosphorus connected species Ph2P-N=PPh2-PPh2=N-PPh2(7). Both compounds were characterized by X-ray crystallography, 1H ,31P 1H}, 13C 1H} NMR, IR, Raman and mass spectra.
