Reaction of (E)-O-arylbenzaldoximes with sodium methoxide in methanol: Reaction of (E)-O-arylbenzaldoximes with sodium methoxide in methanol. Effect of leaving group upon nitrile-forming transition state. Cho, Bong Rae; Jung, Jinhee; Ahn, Eun Kyung (Dep. Chem., Korea Univ., Seoul 136-701, S. Korea). J. Am. Chem. Soc., 114(9), 3425-9 (English) 1992. CODEN: JACSAT. ISSN: 0002-7863. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Reactions of (E)-O-arylbenzaldoximes (E)-XC6H4CR:NOR1 [I; X = H, p-MeO, m-Br, p-O2N; R = H, D; R1 = 2,4-(O2N)2C6H3, 2,4,6-(O2N)2(CF3)C6H2, picryl] with MeONa-MeOH have been studied kinetically.There are some commonly used reagents with their cas registry numbers 392-95-0 and 115828-59-6 in this article. The reactions proceed via competing E2 and SNAr reactions, in which the first step is rate-detg. Although the reactions were strongly influenced by the electronic effect of the b- and O-aryl substituents, they were insensitive to the steric effect of the O-aryl group, except that the SNAr reaction was retarded by the CF3 group. For eliminations from I promoted by MeONa-MeOH, the kH/kD value increased and the Hammett r value decreased with better leaving groups. From these results, the effect of leaving group variation upon the nitrile-forming transition state is assessed. .

DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) Section cross-reference(s): 5 Eighteen herbicidal (no data) dinitroanilines I (R, R1 = NO2, CF3, but not R = R1; R2 = Me, Pr, Bu, allyl, CH2CH2OH, etc.; R3 = H, Me, Bu, allyl, CH2CH2OH, etc., or NR2R3 = 1-pyrrolidinyl) were prepd. by heating II with HNR2R3 in aq. Na2CO3. Thus, 161 g II (R = NO2, R1 = CF3) in 330 mL M Na2CO3 was treated with 48 g HNEt2 at 80° over 0.5 h and heated at 80-90° for 2 h to give 182 g crude I (R = NO2, R1 = CF3, R2 = R3 = Et). ..
