The reactions of selected aryldiazonium tetrafluoroborates with Fe(CO)3(PR3)2, [Fe(mnt)2]−, [Fe(cystH)2]2+, and [Fe(CO)2(cyst)2] (mnt = S2C2(CN)2, cyst = SCH2CH(NH2)CO2H ) result in abstraction of the ligand to yield arenediazophosphonium ions, S-(arenediazo)cysteine or the dinitrogen extrusion product ArS(CN)C=C(CN)SAr. Arylazo complexes of iron were not obtained. The products have been characterized and compounds related to S-(arenediazo)cysteine, namely S-(arenediazo)triphenylmethyl mercaptan and S-(arenediazo)sulfones, have been synthesized for a detailed comparison of their Raman spectra. Assignments of ν(N=N) are made on the basis of 15N- and 2H-substitution experiments. The possible involvement of nucleophilic sulfur as a site for the activation and or reduction of complexed dinitrogen in biological nitrogen fixation is proposed.

Ligand Synthesis

A new long-tethered boron-containing (P–B–P)-pincer ligand has been synthesized. This ligand was introduced to Ir to form (P–B–P)Ir(H)Cl complex. Subsequent reaction with nBuLi led to the formation of dihydride complex (P–B–P)Ir(H)2. Both complexes were found to be moderately active for the catalytic dehydrogenation of alkanes.
