Carbene reactions, VIII

Carbene reactions, VIII. Selectivity of nucleophilic carbenes with regard to heterocumulenes. Hoffmann, Reinhard W.; Hagenbruch, Bernd; Smith, David M.Chemicals with cas numbers 62689-10-5 and 32459-62-4 also play role. (Fachber. Chem., Univ. Marburg/Lahn, Marburg, Ger.). Chem. Ber., 110(1), 23-36 (German) 1977. CODEN: CHBEAM. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Product ratios were used to define the selectivities of I and II toward RC6H4NCO (R = H, p-Me, m-Me, p-EtO)/PhNCS reactant systems. The selectivity ratio RC6H4NCO/PhNCS increased in the order (MeO)2C < I < II. .

Offen. DE 3526235 A1 22 May 1986, 55 pp. (Germany) CODEN: GWXXBX. CLASS: ICM: C07C069-773. ICS: C07C069-92; C07C125-067; C07D295-04; C09K019-06; C09K019-08; C09K019-20. APPLICATION: DE 85-3526235 23 Jul 1985. PRIORITY: DE 84-3441936 16 Nov 1984. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 75, 76 Liq. crystal compns. contg. carbonyl compds. are described for use in electrooptical display devices. Esp. useful are compds. of the formula p-R(C6H4)nCO2C6F5 (R = alkyl or alkoxy contg. O and S atoms, cycloalkyl, cycloalkoxy, F, Cl, Br, CN, NO2, or CF3; n = 1 or 2). Thus, a liq. crystal compn. contg. a black dichroic dye mixt. contg. 1,4,5,8-tetraamino-2,7-diphenoxyanthraquinone, Me 1-amino-4-(4-tert-butylthiophenyl)anthraquinone-2-carboxylate, 4-(4-methoxyphenylazo)-4'-benzyloxy azobenzene, and 4-(4-cyanophenyl)cyclohexylpropane 7, 4-(4-cyanophenyl)cyclohexylpentane 15, 4-cyanobiphenyl-4'-ethane 6, 4-cyanobiphenyl-4'-propane 3, 4-cyanobiphenyl-4'-butane 6, 4-(4-cyanobiphenyl)cyclohexylpentane 5.5, 4-cyanoterphenyl-4'-pentane 5.5, 1-(4-pentylcyclohexyl)-4-(4-butylcyclohexylethylene)benzene 18, 4-(4-butylcyclohexyl)-4'-(4-pentylcyclohexylethylene)-2,2'-dihydrostilbene 8.In this experiment, several chemicals are used like 32459-62-4 5, 4-(4-ethoxyphenylcyclohexyl)pentane 18, 4-phenylcyclohexylpentane 5.5, and pentafluorophenyl 4-(chlorobenzoate (I) 1.7 wt.% showed a decreased decay time vs. a I-free control. .
