In the second route and third route, the insertion of benzoylation can effectively protect the active methylol radical and may advantageously be employed to facilitate the separation of cis-and trans-forms of the intermediate. 路线二和路线三中用苯甲酯保护活泼羟基,并可以分离顺式和反式异构体。
The effects of the catalyst dosage and the preparation conditions of HZ-1 zeolite, for example, number of exchange times on the benzoylation of toluene were studied. 并考察了HZ-1沸石交换次数等制备条件和催化剂用量对甲苯的苯甲酰化反应的影响。
Seven new β-DDB derivatives were prepared from gallic acid in 9 steps such as Ullmann coupling reaction, alkylation, benzoylation etc. The structures of these compounds were identified by(()~ 1HNMR.) 以没食子酸为原料,通过Ullmann偶合反应、烷基化、酰基化等9步反应合成了7种-βDDB的衍生物,其结构经1HNMR确认。
This paper is an attempt to study the reacting time and temperature of benzoylation affecting the detection of polyamines, and the detecting method for polyamines in Citrus callus with reversed phase high performance liquid chromatography. 研究了影响多胺测定的苯甲酰化反应的时间和温度,以及用反相高效液相色谱法测定柑橘愈伤组织多胺的条件。
