Process for the production of acid CHLORIDES derived from the Reaction between carboxylic acid and thionyl chloride.Process for the production of acid CHLORIDES from a carboxylic acid with thionyl chloride.URSULA HOFFMANN.
aAcid chlorides are most often prepared by the reaction of a carboxylic acid with either thionyl chloride or phosphorus pentachloride in much the same way that alkyl chlorides are prepared from alcohols 酸氯化物由羧酸的反应在相似情况下经常准备与亚硫酰氯或磷五氯化物烷基氯化物从酒精准备[translate]...
Fig. 9.The three-component reaction of one equivalent of racemic hydroxy acid, optically pureR-α-methylbenzylamine, and 2-formylphenylboronic acid yielding diastereomeric iminoboronate esters (R,R) and (R,S). Reproduced from S.R. Chaudhari, N. Suryaprakash, Three-component chiral derivatizing ...
aone day, Diogenes saw a boy drinking water from his hands by a fountain, so he threw away his cup and became even happier.(see Greece) 一天, Diogenes由喷泉,因此他看见了男孩饮用水从他的手丢掉了他的杯子并且变得更加愉快。(看见希腊)[translate] ...
Abstract: Isotianil [N-(2-cyanophenyl)-3,4-dichloro-1,2-thiazole-5-carboxamide] has beensynthesized in a good yield with high purity by reaction of the key intermediateproduct, N-(2-carbamoylphenyl)-3,4-dichloro-1,2-thiazole-5-carboxamide, withthionyl chloride in N,N-dimethylformamide at ...
The B terminals are expected to exhibit high reactivity due to the high flexibility derived from the ether bonds and less steric hindrance; therefore, higher molecular weights can be expected. Moreover, the B terminals can be utilized as a weak-acid terminal without any end- capping reaction. ...

PROCESS:For example, thionyl chloride is added to the corresponding trans-4-substituted cyclohexanecarboxylic acid expressed by formula IV, to prepare an acid chloride expressed by formula X, which is the reacted with a solution of 4-fluorophenol in pyridine, to give the exemplified compound. ...

In making the esters and amides in place of the acyl halides there can be used the corresponding acids and salts, e.g., veratric acid and sodium veratrate. Beta (3,4-dimethoxybenzamido) ethyl veratrate is made by reacting stoichiometric amounts of hydroxyethylamine and veratroylchloride in...
