Yang, Benyong; Yang, Dehong; Zhang, Guangye; Li, Wenzhuo ( Zhongyuan Institute of Technology, Zhengzhou 450007, Peop. Rep. China). Zhongyuan Gongxueyuan Xuebao, 16(2), 16-19 (Chinese) 2005 Zhongyuan Gongxueyuan Xuebao Bianjibu. CODEN: ZGXHAD. ISSN: 1671-6906. DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Anisaldehyde was synthesized by the reaction of p-hydroxybenzaldehyde derived from the liq. catalysis reaction, with (CH3)2SO4 in alk. medium. The influences of the acidity of the system and esolvent on the reaction and side reactions were also discussed. The solvent methanol can significantly inhibit the side reactions of p-hydroxybenzaldehyde, and the appropriate pH of the system can be beneficial to the selectivity of the reaction. .

CLASS: ICM: C25B003-02. ICS: C07C043-32; C11B009-00; A61K007-46; A23L003-00; A23L003-34. APPLICATION: DE 85-3529074 14 Aug 1985. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 62 Carboxylic acid orthoesters (I; R = C1-4 alkyl; R1 = H, halo, alkyl, aryl, heteroaryl, alkoxy, acyl, cyano) are prepd. by electrochem. oxidn. of II [R2 = Me, CH(OR)2]. A MeOH soln. contg. II [R1 = 4-Me3C, R2 = CH(OMe)2] 894, tris(2,4-dibromophenyl)amine 8.9, NaOMe 9.28 and KO3SPh 8.9 g was electrolyzed at 22-24° and 3.3 A/dm2 using graphite electrodes to give 85% conversion of II to 47% I (R = Me, R1 = 4-Me3C). .
