Syntheses and reactions of WH(CO)2(NO)(P(C6H5)3)2 and related tungsten nitrosyl complexes

The Chemistry of New Nitrosyltungsten Complexes with Pyridyl-Functionalized Phosphane Ligands

“…[21] The NMR chemical shifts and coupling constants of the carbonyl and hydride resonances, as well as the IR stretching vibrations for NO and CO, were found to be essentially identical for the three hydride complexes. Therefore, one can also expect a similar hydridic behaviour, as discussed previously by Berke et al [22,23] for related compounds.…”

Hydride Transfer Reactivity of Mo(L)(H)(depe)2 (L = N, NBEt3)

“…insertions with a wide variety of unsaturated compounds such as CO 2 , [42][43][44][45][46][47][48] ketones and carbonylmetal compounds (Scheme 2). Reaction of 8 with an excess of CO 2 (450 mbar at -196°C) in [D 8 ]toluene indeed proceeded smoothly at room temeperature.…”

Rhodium complexes of 1,3-diaryltriazenes: Usual coordination, N–H bond activation and, N–N and C–N bond cleavage

“…The observed elongation of the Rh(1)-N(1B) bond, which is trans to the Rh(1)-C(1C) bond, may be due to the trans effect of the coordinated 4-methylphenyl fragment [43][44][45]. The bond lengths within the coordinated triazene ligands are also quite usual [14][15][16][17][18][19][20][21][22][23][24]. Absence of any solvent of crystallization in the lattice of 1-CH 3 indicates possible existence of non-covalent interaction(s) between the individual complex molecules.…”

“…These ligands usually binds to a metal center, via dissociation of the acidic N-H proton, as monoanionic bidentate N,N-donor forming a four-membered chelate ring (I) [14][15][16][17][18][19][20][21][22][23][24]. The 1,3-diaryltriazenide anion is a 'short-bite' ligand, which has received continuous and sustained interest in the research field because of its ability to serve as a monodentate [15,[25][26][27], a bidentate chelating [14][15][16][17][18][19][20][21][22][23][24], and also a bridging ligand [28][29][30][31][32][33][34][35][36][37]. The chemistry of the triazene ligands is further important because of their biological relevance [38][39][40].…”
