Syntheses and properties of isocyanide complexes of iron, trans-> (A = BF4 or PF6)

Article abstract of DOI:10.1016/0022-328X(92)85006-I

The complexes trans-> (R = Me, Et, ^tBu, C6H4OMe-4, C6H4Me-4, C6H5, or C6H4NO2-4; A = PF6 or BF4; dppe = Ph2PCH2CH2PPh2) have been prepared either by treatment of a tetrahydrofuran solution of trans- under argon with the appropriate isocyanide, in the presence of Tl>, or upon N2 replacement in trans-> by CNR.The dinitrogen complexes were obtained by reaction of trans- in THF with Tl> under N2.
