acetonitrile, primary and secondary nitriles, using alkylbromides and sodium amide in liquidammonia. By reaction of the in situ formed organometallic Lewis acids [CpM(CO)(PPh3)](+) (M = Fe, Ru) with the novel tertiary nitriles, the complexes [CpM(CO)(PPh3)(NC C-(CRRR3)-R-1-R-2]BF4 were obtained. A di-iron complex was formed with 1,6-dicyanohexane.
and ecologically benign alternatives to transition metals, although their application as molecular catalysts in challenging CH oxidation reactions has remained elusive. An attractive iodine oxidation catalysis is now shown to promote the convenient conversion of carbon–hydrogenbonds into carbon–nitrogen bonds with unprecedented complete selectivity. The reaction proceeds by two interlocked catalytic

rearrangement is "frozen" in the solid state, as shown by solid-state NMR measurements and X-ray single-crystal structural analysis. Insertion of unsaturated compounds or a low-valent metal center into the NSBV C-N bond gave diverse and interesting ring-expansion products. Theoreticalanalysis showed that the localized structure is predominant and that the homoaromatic delocalized structure exists as a minor

A new class of alkylthiophenoxyalkylamine derivatives and methods for preparation are described. The compounds have vasodilating and antispasmodic activity, inhibit blood platelet aggregation and are substantially free of beta-adrenergic blocking effects. They are particularly valuable in the treatment of disease states responsive to vasodilation such as obstructive peripheral vascular diseases and cerebral vascular deficiencies. Representative and preferred embodiments of the invention are N-[3-[4-(methylthio)phenoxy]propyl]octylamine and N-[3-[4-(1-methylethyl)thio]phenoxy]-propyl]octylamine.
