U.S. US 3996130 7 Dec 1976,9 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C10G029-04. NCL: 208243000. APPLICATION: US 74-430565 3 Jan 1974. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) S, naphthenic acids, and compds. of S, N, and O are removed from crude petroleum and petroleum refining products by treatment at 80-120.degree. with complexes or salts of transition metals (i.e., .pi.-complexes of transition metals, salts or .pi.-allylic complexes of Pt-group metals, and carbonyl complexes of transition metals). The reaction products are nonvolatile compds. and are sepd. from the purified petroleum product by distn. or filtration. For max. purifn., the petroleum product is then treated with a chelating agent to remove unconverted organometallic compds. Thus, 250 mL gasoline (b. 50-150.degree., total S 0.018, thiol S 0.0065, and elemental S 0.003 wt.%) was refluved with 0.18g Fe(CO)5 [13463-40-6] for 1.5 h. The soln. changed from dark green to brownish red in color. The reaction mixt.There are some commonly used reagents with their cas registry numbers 37264-96-3 and 12152-72-6 in this article. was cooled, filtered, and boiled with 0.2 g .alpha.,.alpha.'-dypyridyl [366-18-7] until the soln. was decolorized. The reaction mixt. was steam distd. to give an org. layer that contained 0.007 wt.% total S, 0.0003 wt.% thiol S, and no free S. .

CODEN: ORGND7. ISSN: 0276-7333. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Reaction of N,N-diallylbenzamide with Na2Fe(CO)4 and Me3SiCl afforded chelated cis-tricarbonyl[(h2-N-allyl-N-allylamino)(phenyl)carbene]iron(0) directly. The same reaction of N-(3-buten-1-yl)-N-methylbenzamide proceeded with migration of the double bond to the allylic position, giving a mixt. of chelated cis-tricarbonyl[(h2-N-(2-butenyl)-N-methylamino)(phenyl)carbene]iron(0) and nonchelated tetracarbonyl[(N-(2-butenyl)-N-methylamino)(phenyl)carbene]iron(0). N-(3-Buten-2,2-dimethyl-1-yl)-N-methylbenzamide, in which migration of double bond is not possible, gave a mixt. of E and Z isomers of nonchelated tetracarbonyl[(N-(2,2-dimethyl-3-butenyl)-N-methylamino)(phenyl)carben e]iron(0). Thermolysis of the latter furnished 1-methyl-3,3-dimethyl-6-phenyl-1,2,3,4-tetrahydropyridine as the only product.
