    Abstract

    Reaction of [{K(dme)}{(ONO)V≡N}]2 ([ONO]3− = anilide‐bis(aryloxide)) with elemental sulfur afforded an anionic thionitrosyl complex [K(dme)4][(ONO)V(NS)], which could be isolated as a dark red solid. The solid‐state metrical parameters suggest that it is best described with a thio‐imido resonance form. The thionitrosyl complex was shown to react with a variety of substrates at the thionitrosyl sulfur atom and across the V–N bond. Reaction with PPh3 occurred with sulfur atom transfer to form the nitride and SPPh3. The thionitrosyl complex underwent S‐alkylation with alkyl halides to form a sulfenylimido complex [(ONO)V(NSR)] (R = Me, CH2C6H4‐4‐Me). Reactions with Me3SiCl and BPh3 resulted in the formation of [(ONO)V(NSiMe3)] and [K(dme)4][(ONO)V(NBPh3)] along with concomitant loss of sulfur. When treated with CO2, CS2, and PhNCS, the reactions took place across the V–N bond to generate [(ONO)VE] (E = O, S). The thionitrosyl complex was unstable in toluene and underwent dimerization via loss of K2S to afford [{(ONO)V}2(μ‐NSN)]. Reaction of the thionitrosyl complex with [Cp2Fe][PF6] gave a mixture of products containing the NSN complex and [{(ONO)V}2(μ‐NSSN)].

    Abstract

    Here we show that a tridentate bis(aryloxide)anilide‐ligated titanium/potassium scaffold promotes functionalization of coordinated N2 with CO2 and CS2 through formation of N−C bonds. Treatment of a naphthalene complex with N2 gave an end‐on bridging dinitrogen complex featuring a [Ti2K2N2] core. The dinitrogen complex underwent insertion of CO2 into each Ti−NN bond to afford an N,N′‐dicarboxylated hydrazido complex. Stepwise nitrogen‐carbon bond formation at coordinated N2 proceeded to afford an unsymmetric hydrazido complex upon sequentially treating the dinitrogen complex with CS2 and CO2. Addition of Me3SiCl to the dicarboxylated hydrazido complex resulted in partial silylation of the carboxylate groups but did not lead to removal of the functionalized N2 unit from the metal centers. However, reduction of the dicarboxylated hydrazido complex with potassium naphthalenide afforded an oxo‐bridged dinuclear complex along with release of free potassium cyanate.

    Abstract

    Nitrogen–carbon bond‐forming reactions at coordinated dinitrogen in a bifunctional titanium–potassium system are reported. A titanium atrane complex with a tris(aryloxide)methyl ligand (1) was treated with two equivalents of potassium naphthalenide under N2 atmosphere to generate a bifunctional complex (2) in which N2 binds end‐on to two titanium centers and side‐on to three potassium cations. Dinitrogen complex 2 reacted with carbon dioxide, tert‐butyl isocyanate, and phenylallene, forming nitrogen–carbon bonds and affording diverse N‐functionalized products. The reaction of 2 with CO2 followed by addition of Me3SiCl resulted in the formation of the starting complex 1 with concomitant release of silylated carboxyl hydrazines while the reaction with two equivalents of tert‐butyl isocyanate proceeded by insertion into the Ti−N bonds. Treatment of 2 with phenylallene afforded vinyl‐substituted hydrazido complexes.

First, new ligands consisted of aryloxides were prepared as supporting ligands for the iron complexes. Iron complexes with bulky aryloxides can be applied for synthesis of highly reactive iron nitrides, which were structurally characterized by X-ray crystallographic analysis.
