标题 :Synthesis of indoles from anilines and intermediates therein
发明人：GASSMAN PAUL G
权利人:UNIV OHIO STATE RES FOUND
摘要:Preparing indoles and intermediates therefor by reacting an Nhaloaniline with a Beta -carbonylic hydrocarbon sulfide to form an azasulfonium halide, reacting the azasulfonium halide with a strong base to form a thio-ether indole derivative, and then reducing the thio-ether indole, e.g. with Raney nickel, to form the indole compound. When an acetal or ketal of the Beta carbonyl hydrocarbon sulfide is used, the azasulfonium salt is treated with a base, and then with an acid to form the thio-ether indole derivative. When an Alpha -ethyl- Beta -carbonylic hydrocarbon sulfide is used, the resulting azosulfonium salt reacts with strong base to form a thio-ether indolenine derivative, which on reduction with Raney nickel or complex metal hydrides yields 3-substituted indoles. The aniline may be an aminopyridine to form an aza-indole compound in the process. The azasulfonium salts and thio-ether indole or thio-ether indolenine derivatives can be isolated and recovered from their respective reaction mixtures. The thio-ether-indole and thio-ether indolenine derivatives are useful as intermediates to make the indoles without the thio-ether group. The indoles are known compounds having a wide variety of uses, e.g., in making perfumes, dyes, amino acids, pharmaceuticals, agricultural chemicals and the like.

标 题:Novel molybdenum oxycarbonitride compositions
发明人：MCCANDLISH LARRY E; TURAEW LARISSA W
权利人:EXXON RESEARCH ENGINEERING CO
摘要:Novel molybdenum oxycarbonitride compositions are described together with a general method of synthesis. The compositions can be obtained by the relatively low temperature thermal decomposition of an amine molybdate and can be amorphous, poorly crystalline, or substantially crystalline, and can unexpectedly possess high surface areas in the region of about 60 to 130 m2/g and higher. The compositions have the general formula: MoOaCbNc, where a, b and c are non-zero decimal values and the sum: a+b+c, is less than or equal to about one, as evidenced by X-ray diffraction and chemical analyses. The compositions are useful as abrasives, as for removing oxide coatings from metals.
