Resorcinol and substituted resorcinals: Resorcinol and substituted resorcinals. Greco, Nicholas P. (Koppers Co., Inc. , USA). Ger. Offen. DE 3302848 A1 3 Nov 1983, 31 pp. (German).In this article, certain chemicals are used. Some of their cas registry numbers are 13984-50-4 and 108-46-3 (Germany). CODEN: GWXXBX. CLASS: IC: C07C039-08; C07C037-07. APPLICATION: DE 83-3302848 28 Jan 1983. PRIORITY: US 82-372030 26 Apr 1982. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 24 Resorcinols (I) (R-R4 = H, C1-6 alkyl) were prepd. Thus, MeCO(CH2)3CO2Me was cyclized over activated C to give 3-hydroxy-2-cyclohexen-1-one (II), which was dehydrogenated over 5% Pd-C to give resorcinol. Data for several runs were given. .

(United States of America). CODEN: USXXAM. CLASS: IC: C07C045-45. NCL: 568346000. APPLICATION: US 81-303541 18 Sep 1981. DOCUMENT TYPE: Patent CA Section: 24 (Alicyclic Compounds) Cyclohexanediones I (R-R7 = H, alkyl) were prepd. by cyclization of R8O2CCRR1CR2R3CR4R5CHR6R7 (R8 = alkyl, aryl, alkaryl) over a C catalyst in the presence of a carrier which was liq. at 25°. Thus, MeO2C(CH2)3COMe (II) in PhMe was passed over activated C at 400° to give cyclohexenone III with 36% II conversion. PhMe was removed from II and III by distn. at 50° under reduced pressure. .
