傅克反应是傅克烷基化反应(Friedel-Crafts alkylation)和傅克酰基化反应(Friede-Crafts acylation)的统称,简称傅克反应或FC反应。 (Charles Friedel, 1832-1889) 通常意义的傅克反应指的是傅克酰基化反应,主要用于制备芳香酮,再以芳香酮为过渡,制备芳香胺、芳香肟、芳香醇、烷基香芳环等,是有机化学中最重要的反应...

NMR(核磁共振波谱法)是研究原子核对射频辐射的吸收,是对各种有机和无机物的成分、结构进行定性分析的最强有力的工具之一,有时亦可进行定量分析。 核磁共振是有机化合物结构鉴定的一个重要手段,一般根据化学位移鉴定基团;由偶合分裂峰数、偶合常数确定基团联结关系;根据各H峰积分面积定出各基团...

After reduction, gel pieces were washed with 100% ACN and, for alkylation, incubated for 30 min at RT in the dark in 55 mM iodoacetamide/25 mM ABC to block reactive cysteine groups. After washing with 25 mM ABC and 100% ACN, gel bands were dried in a centrifugal vacuum ...
第八章烷基化(Alkylation) 第一节概述 一、烷基化反应概念 把烃基引入有机化合物分子中的C、N、O等原子上的反应称为烷基化反应,简称烷基化。所引入的烃基可以是烷基、烯基、芳基等。其中以引入烷基(如甲基、乙基、异丙基等)最为重要。 广义的烷化还包括引入具有各种取代基的烃基(—CH2COOH、—CH2OH、—CH2Cl...

Upon mild reduction and alkylation of these (Fc)5's their C1-fixing capacity reverted to being approximately the same (60 g) irrespective of temperature of production. (Fc)5 was also prepared at 25°C in the presence of 5 M urea, purified by immunoadsorption as before and aliquots then ...
