Acetic acid, secondary butyl ester

Synonyms 2-Butanol acetate acetic acid, secondary butyl ester... 

Olefins add anhydrous acetic acid to give esters, usually of secondary or tertiary alcohols propylene [115-07-1] yields isopropyl acetate [108-21-4], isobutylene [115-11-7] gives / /7-butyl acetate [540-88-5]. Minute amounts of water inliibit the reaction. Unsaturated esters can be prepared by a combined oxidative esterification over a platinum group metal catalyst. For example, ethylene-air-acetic acid passed over a palladium—lithium acetate catalyst yields vinyl acetate. 

The types of compounds presently known to donate a hydrogen atom to photoexcited quinones include aldehydes, primary and secondary alcohols, esters and lactones, ethers and thioethers, olefins having allylic hydrogen atoms, alkylbenzenes, benzene, and saturated hydrocarbons. This list is undoubtedly incomplete. Acetone, methyl ethyl ketone, acetic acid, and -butyl alcohol react extremely slowly. 

The synthesis of benzyloxycarbonyl (31) derivatives by the amino-lysis of various active esters of benzyl carbonate has been reported The use of JV-hydroxypiperidyl methoxybenzyl carbonate and JV-hydroxypiperidyl f-butyl carbonate for the synthesis of -methoxy-benzyloxycarbonyl and f-butyloxycarbonyl (45) derivatives, respectively, has been described The benzhydryloxycarbonyl group (35) could be removed by the action of boron trifluoride in glacial acetic acid . The use of easily cleaved, optically active, protecting groups of the urethane type for the resolution of racemic primary and secondary amines was reported .
