The work herein described resulted from the investigation on the Wohl-Zieglerreaction of para-methylanisole under different conditions.It was found that solventplayed an important role in the selective bromination.With carbon tetrachloride,side chain bromination was favored in 65% yield,while with glacial acetic acidring hromination was favored in 68% yield.During the reaction of N-bromosuc-cinimide(NBS)on anisole,liberation of bromine and then some hydrogen bromidegas were observed.These findings prompted a further study of the reaction of NBSon several solvents such as carbon tetraehleride,chloroferm,benzene and benzoni-trile.Time of bromine liberation from these solvents has been determined andbenzoyl peroxide in every case served as a promoter.Therefore,the ring bromina-tion of these aryl ethers by means of NBS has been assumed to proceed via a rea-ction mechanism practically identical to the ring bromination by bromine.Fromthis assumption,we have tried to explain:(1)Why either aluminium chlorideor bonzoyl peroxide would serve as promoter in the ring bremination,(2)whym-methylanisole and resercinol dimethylether would be easily ring-brominatedoven in carbon tetrachloride,and(3)why m-methylanisole would not be bromi-hated easily on the side chain.Selective bremination of p-methoxy-acetophenonewas aide studied and 2,4-dimethoxy-5-bromobonzoic acid has been convienentlyand successfully synthesized from 2,4-dimethoxybenzene in three steps.Further studies on the Wohl-Ziegler reaction of p-methoxy-ethylbonzene and2,4-dimethoxyethylbenzene were made.The former would be easily brominated onthe side chain as predicted,while the latter even in carbon tetrachloride brominatedin the ring and would undergo side chain bromination only when an additionalmole of NBS was added.The results indicated that ring bromination was preferreddue to the highly activated benzene nuclei.And the orientation of ring bromina-tion which has been also determined was shown to be what one would expect fromelectrophilic mechanism of bromine ring-bromination.

本文报告对-甲苯甲醚在不同情况下与 N-溴代丁二酰亚胺(NBS)的作用。作者认为溶剂是使溴化反应具选择性的一种重要因素。用四氯化碳则可以得到收率为65%的侧链溴化产物,如用冰醋酸则得到收率为68%的苯环溴化产物。我们在研究苯甲醚与 NBS 作用时,观察到有溴放出,而后又有溴化氢气体出现,由于这些现象,使我们进一步研究 NBS与数种溶剂,例如四氯化碳,氯仿,苯及苯腈的作用。同样发现都在不同的时间内能放出溴,并且过氧化苯甲酰对于在每一种上述溶剂中进行的反应都具催化作用,加速放出溴。我们认为芳香醚与 NBS 所进行的苯环溴化的反应机构基本上是与溴的苯环溴化的反应机构相同。据此我们可以解释,(1)何以三氯化铝与过氧化苯甲酰都能够作为苯环溴化的催化剂,(2)何以间-甲苯甲醚与间-二甲氧基苯即使在四氯化碳中也容易苯环溴化,以及(3)何以间-甲苯甲醚不易进行侧链溴化,此外也研究对-甲氧基苯乙酮的侧链溴化与苯环溴化。我们研究对甲氧基乙苯与2,4-二甲氧基乙苯的溴化反应,发现前者很容易进行侧链溴化,这是符合于游离基丙烯型溴化反应机构的,而后者即使在四氯化碳中首先是苯环溴化,如果再加一克分子 NBS,则第二个溴原子能...

In presence of certain catalysts, such as organic peroxides, organic bases, platinium or other metallic compounds, or in absence of catalysts but being radiated by ultraviolet light or γ-rays, or simply by heating under higher pressure, silanes of the type, RR'R''SiY, where R'S may be alkyl, aryl or alkoxy groups or halogen atoms and Y may be either a hydrogen or an alkalie metal atom, can be added to the unsaturated compounds containing carbon-carbon or carbon and other elements(such as oxygen or nitrogen)multiple bonds to form the coresponding substituted silanes. The manipulation of the reactions are relatively Simple and the yields of the reaction products are often fairly good and in some occasions even quantitative. Thus, it may be a hopeful way to synthesis various valuable monomers of organosilicon poly-mers through these reactions. In present review article, the literature data about this subject since the discovery of the reaction till 1961(and a few of 1962)have been collectec and discussed on a theoretical as well as a practical view.

硅烷类在过氧化物,紫外线,有机碱,铂,钯或其它金属化合物存在下,或在高温高压下,或以r-射线照射,能与烯烃或炔烃以及它们的衍生物进行加成得到对应的烃基硅化合物;其中以H Si X_3最容易进行加成,H Si R X_2,H Si R_2 X次之;H Si(OR)_3,H Si R_3(R=C_6H_5例外),Si X_4最难,不饱和烃中碳链分枝愈多,加成愈困难。催化剂中以铂催化剂(pt石棉,H_2 Pt Cl_6,pt/c)应用范围最广,催化效能最高,并且不致引起易聚合的烯烃发生聚合,硅烷与含碳氧或碳氮或氮氮双键进行加成反应时,硅烷基总是加在杂原子上。这个反应是制备含长链烃基,具取代基的烃基及(?)基硅烷类的捷便方法。配合我国硅有机聚合物的生产,这方面研究工作是亟待展开的,尤其硅烷与烯烃间的调聚反应,与那具有取代基烯烃及炔烃的加成反应特别值得令人注意。
