Lubricating oils having improved antioxidant and antiwear properties are obtained by adding a minor amount of a reaction product made by reacting an olefinic hydrocarbon containing about 6-18 carbon atoms and about 1-3 olefinic double bonds concurrently with sulfur and hydrogen sulfide to obtain a reaction intermediate and reacting this intermediate with additional olefin hydrocarbon which may be the same or different. Preferred olefinic hydrocarbons are dicyclopentadiene and alloocimene.

91 CONVERSION OF ALKANES TO ORGANOSELENIUMS AND ORGANOTELLURIUMS EP14833997 2014-08-06 EP3030635A4 2016-07-27 PERIANA ROY A; KONNICK MICHAEL M; HASHIGUCHI BRIAN G
The invention provides processes and materials for the efficient and costeffective functionalization of alkanes and heteroalkanes, comprising contacting the alkane or heteroalkane and a soft oxidizing electrophile comprising Se(VI) or Te(VI), in an acidic medium, optionally further comprising an aprotic medium, which can be carried out at a temperature of less than 300 C. Isolation of the alkylselenium or alkyltellurium intermediate allows the subsequent conversion to products not necessarily compatible with the initial reaction conditions, such as amines, stannanes, organosulfur compounds, acyls, halocarbons, and olefins.

95 PROCEDE ET REACTIF DE SULFONYLATION UTILES POUR LA SYNTHESE DE SULFANILIDE PERHALOGENE EP99954061.0 1999-11-04 EP1127036A1 2001-08-29 DESMURS, Jean-Roger; MILLET, André; PEVERE, Virginie
The invention concerns a method and a reagent useful for the synthesis of perhalogenated sulphanilide on the carbon borne by the sulphur atom of the sulphanilide function. Said perfluoroalkane sulphonylation method is characterised in that it comprises a step which consists in contacting a nucleophile whereof the nucleophilic atom is a nitrogen, with a reagent comprising by successive or simultaneous addition a heavy sulphonyl halide, advantageously sulphonyl chloride, and an organic base comprising a metalloid atom having resonance with a π bond, and the organic part of said sulphonyl is perhalogenated, advantageously perfluorinated, on the carbon borne by the sulphur. The invention is applicable to intermediate synthesis for organic chemistry.
