benzoyl chloride, phthalic anhydride and acetyl chloride giving 85–90% yields. The perhydrolysis of benzoyl chloride has been shown to proceed, partially at least, through the intermediary formation of benzoyl peroxide.doi:10.1016/S0040-4020(01)92300-2Y Ogata...
the advantages of hydrolysis methods to reduce p-toluene sulfonyl chloride were discussed. 主要介绍了四种二氯苯甲醛的合成工艺路线,并比较利弊,阐述了对甲苯磺酰氯氯化水解法的优越性。 18.However, one major defect of applying starch material to the affinity adsorption is the easy hydrolysis of starch ...
This invention relates to a novel process for the preparation of optically pure L-(+)-ergothioneine. The process for the chemical synthesis of L-ergothioneine comprises steps which consist of reacting L-histidine alkyl ester with an acid halide, chlorofo
In this work, the induced photo-degradation of poly styrene –co-butadiene films in the air has been studied (for 400 hr.) in the presence and absence of TiO2 dye and Ni complex, benzyl bis(benzoylhydrazone) Ni, as a photosensitizer by a... SS Kadhium,EM Hussen,ZN Mageed,... - 《...
ChemInform Abstract: Synthesis of β-Arylvinyl Ethers by the Palladium-Catalyzed Reaction of Aroyl Chlorides with Vinyl Ethers The benzoic acids (I) are converted to the corresponding benzoyl chlorides which are directly treated with butyl vinyl ether in the presence of palladium a...

Kinetic data for the neutral hydrolysis in aqueous solutions of 1 -acetyl-1,2,4-triazole and 1-benzoyl-3-phenyl-1,2,4-triazole have been analysed to yield the dependences of rate constants on temperature under isobaric and isochoric cond... JBFN Engberts,JV Haak,MJ Blandamer,... - 《...
Both 2,2-dimethyl-3-oxo-β-sultam 136 and N-benzoyl-β-sultam 138 underwent amine-catalyzed hydrolysis affording the corresponding sulfonic acids 137 and 139 through cleavage of the S–N bond. Once again, no product resulting from the cleavage of the C–N bond was observed. This could ...
Transition-state structure and reactivity in the acid-base-catalyzed hydrolysis of a model intermediate for corn-plant herbicide resistance The intermediate formed by nucleophilic displacement of chloride from the herbicide Cyprazine (2-chloro-4-isopropylamino-6-cyclopropylamino-s-triazine) by ... NI ...
In one embodiment, the hydrolysis promoting group is stereospecifically attached to the a-carbon of the hydrophobic taxane. The Substitution of an HPG for the methylene unit ordinarily occupying the alpha position allows for enhanced in vivo hydrolysis of the hydrocarbon-taxane bond, and hence, for...
Sturrock2 & K. Ravi Acharya1 Angiotensin-I converting enzyme (ACE) is a zinc dipeptidylcarboxypeptidase with two active domains and plays a key role in the regulation of blood pressure and electrolyte homeostasis, making it the principal target in the treatment of cardiovascular disease....
