Synthesis, characterization, and exchange of complexes of (R)-N,N-dimethylaminoethylferrocene with SO₂ and BF₃

Abstract

. J. Chem. 67, 93 (1989).Sulfur dioxide and (R)-N,N-dimethylaminoethylferrocene (I) react with an enthalpy of formation of 21.5 * 1 kcal mol-' to give a complex with sulfur bonded to nitrogen. The SO2 exchanges between adduct molecules by a dissociation mechanism. BF3 reacts with the above amine to give an adduct and its partly hydrolyzed product, [Traduit par la revue]

Galaxy rotation curves from general relativity with renormalization group corrections

“…The latter is a recent relativistic proposal that is capable of dealing with galaxy rotation curves and other phenomena usually attributed to dark matter. For galaxy rotation curves phenomena, STVG becomes equivalent to a similar proposal called MSTG [22,23,24]. The model parameters that we use to fit galaxies in the STVG framework can be found in ref.…”

“…Other nonbridging ligands may be attached to copper(II), such as halides (Jackson et al, 1996;Belford et al, 1972;Fu & Chivers, 2007;Harlow Simonsen, 1977), oxygen-bonded ligands (Churchill & Rotella, 1979;Bertrand & Kelley, 1966), nicotine (Haendler, 1990), oxoamines (Weinberger et al, 1998), pyridine (Nä ther & Jess, 2002;Gill & Sterns, 1970;Duncan et al, 1996;Kilbourn & Dunitz, 1967), imidazole (Zhang et al, 2003;Norman et al, 1989;Erdonmez et al, 1990;Clegg et al, 1988;Corté s et al, 2006), pyrazole (Keij et al, 1991;Liu et al, 2003), triazole (Skorda et al, 2005), tetrazole (Lyakhov et al, 2004), azaindole (Poitras & Beauchamp, 1992), phosphine (Bertrand, 1967), thiazole (Bolos & Christidis, 2002), sulfimide (Kelly et al, 1999), phosphite (Churchill et al, 1975) or sulfoxide (Brownstein et al, 1989;Guy et al, 1988).…”

Copper(I)‐Assembled Pseudorotaxanes Bearing Bis(nitrile) Ligands: Selective Formation of Large Chelate Rings

“…[13] On the other hand, a slightly longer Cu I ϪN distance was measured in the tetrakis benzonitrile Cu I complex [Cu(PhCN) 4 ][SbCl 6 ] (2.05 Å ). [14] Selected bond lengths and bond angles are given for both complexes in Tables 1 and 2.…”
