内容記述 | In the previous paper,it was our investigation that the self-condensation of benzyl halides and the benzylization of phenols both occur simultaneously as competitive reaction when the mixtures of phenols and benzyl haildes,in which the existing quantity of the former to the latter being 1:1 or the more in mole ratio,were treated with gritty aluminum for the condensation by dehydrohalogenat ion. Since these reactions with aluminum needed the addition of some quantity of nitrobenzene,similar reactions with iron is now carried out without this addition. The results obtained are as follows: (i) Using iron powder,benzylization of phenols by benzyl halide smoothly proceeded to the considerable yield,and it is presumed that the iron halide produced as the intermediate product may catalyze the alkylation. (ii) From the determined values of mean molecular weight for the respective reaction products,it was shown that the phenols were mono- and di-benzylized,and the benzyl halides di- and tri- benzylized. (iii) Some information was obtained for the reaction temperature dependance of mean molecular weight of self-condensation products and benzyl phenols having maximum at the specific reaction temperature for respective sort of phenols. (iv) In the benzylization of phenols,p-benzyizlation was easier at lower temperature and o-benzylization at higher temperature. |
