Reaction of oligomeric Cu(I) complexes [Cu(Μ-S-C(=NR)(O-Ar-CH3)]n with Lewis acids gave Cu(I) carbene complexes, which were characterized by1H and13C NMR spectroscopy. Cu(I) carbene complexes could be directly generated from RNCS, Cu(I)-OAr and Lewis acids; this method can be used to prepare Cu(I) carbene complexes with different substitutents on the carbene carbon. The complexes were unreactive towards olefins and do not undergo cyclopropanation. Electronic structure calculations (DFT) show that the charge on the carbene carbon plays an important role in controlling the reactivity of the carbene complex.

Atmospheric N2 can be cleaved directly to yield metal-nitride (before proceeding to the functionalization of N$_\alpha$ of coordinated N2) and subsequently functionalized to ammonia using M(III)(NMe2)3 (M = W/Mo) as a catalyst, and suitable proton and electron sources. The calculated energies of thermodynamic and kinetic states of the various intermediates and transition states in the reaction coordinate to yield ammonia confirmed the viability of the proposed reaction pathway. Rationale of different pathways have been examined and discussed in detail. Changes in the structural features of the catalyst and some important intermediates and transition states have also been examined.

DFT studies have been executed on a hypothetical Ru-triamidoamine complex to understand the possibility of synthesizing ammonia and hydrazine from the dinitrogen at normal temperature and pressure in heptane. In this present study, we utilized the H2 in the form of FLP-H2 complex and reacted with Rutriamidoamine complex. We have added three H+ and H- parts of FLP-H2 to the Ru complex in a stepwise manner as an alternate way to yield NH3/N2H4. The catalytic cycle for the formation of NH3 and N2H4 were found to be energetically feasible. We have also observed some thermodynamically feasible six coordinate
