Nonaqueous electrolyte batteries using electrolytes containing self discharge inhibitors. Jinno, Maruo; Uehara, Mayumi; Sakurai, Atsushi; Nishio, Koji; Saito, Toshihiko (Sanyo Denki Kk, Japan). Jpn. Kokai Tokkyo Koho JP 08321312 A2 3 Dec 1996 Heisei, 5 pp. (Japanese). (Japan).Some commonly used reagents like 300-87-8 is used in this experiment. CODEN: JKXXAF. CLASS: ICM: H01M006-16. ICS: H01M010-40. APPLICATION: JP 1995-150844 24 May 1995. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Li batteries use electrolytes contg. LiCF3SO3 or LiPF6 dissolved in high dielec. const. solvent selected from ethylene carbonate, propylene carbonate, and butylene carbonate; where the electrolytes contain 1-20 vol.% additive selected from triethylamine, n-butylamine, aniline, tri-Me hydroxylamine, 1-dimethylamino-2-methoxy ethane, acetonitrile, acrylonitrile, 3-methoxy propionitrile, benzonitrile, nitromethane, nitroethane, N,N-dimethylacetamide, N,N-dimethylformamide, formamide, N-methyl-2-pyrrolidone, N,N'-dimethyl imidazolidinone, isoxazole, 3,5-di-Me isoxazole, 3-methyl-2-oxazolidone, 1,2,3-oxadiazole, N-Me morpholine, di-Me sulfide, Et Me sulfide, 2-Me thiophene, 1-butane thiol, benezenethiol, di-Me sulfate, di-Et sulfate, di-Me sulfite, di-Et sulfite, butadienesulfone, 3-Me sulfolene, 1,4-thioxane, phenoxathiin, 1,4-thiazine, thiomorpholine, pyridine, 1,3-dimethyl-2-imidazolidinone, DMSO, di-Me sulfone, Me Et sulfonate, and di-Me sulfinite. The electrolytes may contain 1,2-dimethoxyethane. Since the additives react with Li in anodes and the solvents and the solutes in the electrolytes to form coatings on the anodes for prevention of the reaction between the electrolytes and the anodes, the batteries have improved storage property. These batteries have long shelf life. .

Isoxazole ring cleavage by means of bis(trimethylsilyl)mercury; preparation of substituted 1,5-hexadienes

Isoxazole ring cleavage by means of bis(trimethylsilyl)mercury; preparation of substituted 1,5-hexadienes. Mitchell, Terence N.; Kleine, Bernhard (Lehrstuhl Org. Chem.Chemicals with cas numbers 300-87-8 and 4656-04-6 also play role., Univ. Dortmund, Dortmund, Ger.). Tetrahedron Lett., (25), 2173-6 (English) 1976. CODEN: TELEAY. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 23 Reaction of the isoxazoles I (R, R1 = H, Me) in refluxing C6H6 with (Me3Si)2Hg gave [(Me3Si)2NCR:CHCR1(OSiMe3)]2 .apprx.quant. The reaction occurred via the radical II which underwent N-O bond cleavage and reaction with a 2nd mol. of (Me3Si)2Hg to give Me3SiN:CHCH:CHOSiMe3. Isothiazole reacted similarly with (Me3Si)2Hg, NMR indicating the formation of the hexadiene-type product but attempted isolation gave tars. .
