Rh(COE)2Cl]2 in the presence of IMes, MA -bis-[2,4,6-(trimethyl)phenyl]imi-dazol-2-ylidene, reacted with at room temperature to give the trigonal bipyrami-dal [Rh(H)2Cl(IMes)2] 6 (which is analogons to 3) via intermediate formation of the isolable cyclometallated 5 (Scheme 2.2) [3],... 

Carbene ligands can replace phosphines dne to similar electronic properties. The development of NHC design concepts featnring different substituents and backbones eventually culminated in the most prominent derivative, the SIMes (SDVtes = A, A -bis[2,4,6-(trimethyl)phenyl]imidazolidin-2-ylidene) ligand that is nsed in the second and later also third generation catalysts (complexes 72, 73, 74b and 74c in Fig. 3.28) [105, 109, 114,116],...

In the nitrogen and boron analogs depicted in Scheme 3-52, two methyl groups provide a sufficient shielding at the NR2 centers (R = Me), while two mesityl groups are needed for protection of the BR2 centers (R = 2,4,6-trimethyl phenyl). Electrochemical studies of l,4-bis(dimesitylboryl)benzene have shown two well-separated one-electron reduction processes, with the formation of the corresponding anion radicals and dianions, respectively (Fiedler et al. 1996). According to UV/vis/near-IR and ESR spectroscopic data... 

Sind in den beiden Phenyl-Gruppen des 1,8-Bis-[phenylathinyl]-naphthalin jeweils die 2,6-Stellungen durch Methyl-Gruppen besetzt (z. B. 2,4,6-Trimethyl-phenyl-Restc), so wird keinBenzo-[k]-fluoranthen gebildet, weil dazu mindestens eine freie o-Positionnotig ist. In diesem Fall entsteht nur noch das entsprechendc Azulen-Derivat-5.

In an extensive study of the amide metabolites of -benzylanilines, Ulgen et al. [898], tabulated the retention times for 43 compounds on a C g column (A = 254nm). A series of isocratic acetonitrile/water mobile phases were used. Typically, sets of four or five compounds were separated. For example, benzalde-hyde, 2,4,6-trimethylaniline, A -benzoyl-2,4,6-trimethylaniline, V-(2,4,6-trimethyl-phenyl)-a-phenylnitrone, and iV-benzyl-2,4,6-trimethylaniline were baseline resolved in 30 min using a 40/60 acetonitrile/water (phosphate buffer at pH 7) mobile phase. The results for six other sets of analytes were tabulated as well. Typical acetonitrile/water (phosphate buffer at pH 7) mobile phase compositions ran from 40/60 to 50/50. Elution times varied between 2.5 and 36 min. If the other separations are anything like the one seen in the only chromatogram shown, (bis is a very valuable and thorough set of results. 

Spin-spin couplings between nitrogen and silver nuclei, /nAg, and Ag chemical shifts provided useful structural information on silver complexes obtained by Scheele et in the reaction of 3,5-bis[3-(2,4,6-trimethyl-phenyl)imidazolium-1 -ylmethyl] -1 Ff-pyrazole bishexafluorophosphate and 3,5-bis[3-(2,6-diisopropylphenyl)imidazolium-l-ylmethyl]-l.ff-pyrazole bishexafluorophosphate with Ag20. The latter complex is not stable in solution but exists in equilibrium with tetra- and hexanuclear complexes.
