I’d prefer to use benzoyl chloride too. Reply Alexander Williams June 28, 2018 at 2:21 pm Why does the carboxylic acid need to be in excess over the alcohol in this reaction? It is something I found out today in lab and do not understand why. Reply Jame...
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...
The substrates are heated with an acid catalyst such as toluene-p-sulfonic acid <87HCA448, 89HCA690>, acetic acid or sulfuric acid <78JOC1248> or DOWEX 50 <70TL4095, 87HCA448> in benzene, toluene or dichloromethane. The reaction is quite versatile, and derivatives have been prepared from...
The simplest series of carboxylic acids are the alkanoic acids(RCOOH)where R is a hydrogen or an alkyl group.Compounds may also have two or more carboxylic acid groups per molecule.The mono-and dicarboxylic acids have trivial names. Carboxylic acid radical ...

into an acid chloride. This is helpful for us synthetically because once you have an acid chloride, you can turn that into any other derivative because of how reactive it is in very high yields. Awesome. Let's move on to the synthesis of amines....
(of., for example, DE 4 115 184), the starting material used in the present case, the starting materials are particularly readily accessible and inexpensive cinnamic acid derivatives whose reaction with thionyl chloride yields the benzothiophenecarboxamides of the formula (IIb) required in a smooth...
