Phenols and Phenol ethers. 



In conjunction with his collaborators A. Blumenthal and 

 K. Kowerski, C. A. Bischoff 1 ) has studied the conversion of the 

 carvacryl and thymyl esters of a-bromo-fatty acids with 

 sodium carvacrylate and thymylate respectively, and obtained 

 products with a normal chain. The above-mentioned esters were produced 

 in the usual manner by conversion of the bromides of a-bromo-propionic, 

 butyric, isobutyric, and isovaleric acids with thymol and with carvacrol, 

 or preferably its sodium compound. The a-brominated esters obtained, 

 when again treated with the sodium salts of the phenols in question, 

 yielded carvacryl esters of the a-carvacroxy fatty acids, and thymyl 

 esters of the a-thymoxy acids respectively. 



Anethol. J. Th. Henrard 2 ) found that anethol and methyl 

 chavicol, on reduction with nickel and hydrogen, are quantitatively 

 converted in p-propylanisol (b. p. 213,5 to 2I 4>5°> corr.). 



Apiol. For the elucidation of the constitution of apiol we are 

 indebted to Ciamician and Silber, and also to Thorns 3 ). Both 

 apiols are converted by alcoholic potash liquor or sodium ethylate in 

 the corresponding isoapiols, the nitrosites of which are described in 

 a work just published by E. Rimini and F. Olivari 4 ). The nitrosite 

 of dill apiol C 12 H 14 7 N 2 is a fine yellowish powder melting at 134 

 with decomposition, and yields with piperidine, suspended in alcohol, 

 when carbonic acid is passed through the filtrate, the corresponding 

 ^-nitroisoapiol, C 12 H 13 6 N, m. p. 94 to 95 . The /3-nitroisoapiol from 

 parsley apiol, produced in an analogous manner, melts at 9 6°. In 

 aqueous-alcoholic solution this body is converted with hydroxylamine 

 hydrochloride and soda, in apiolaldoxime of the m. p. 160 . By the 

 action of piperidine on the nitrosites, small quantities of an aldehyde 

 are formed, no doubt owing to secondary influences of the piperidine 

 on the nitro compounds. 



Asarone. According to R. Fabinyi and T. Szeki 5 ), asarone 

 cannot be nitrated, as it then resinifies. But the authors were able 

 to produce a nitro body by nitrating asaronic acid with glacial acetic 

 acid and nitric acid; the carboxyl-group is thereby split off and sub- 

 stituted by the nitro-group. If the 1, 2, 5 -trimethoxy-4 -nitrobenzene, 

 (CH 3 0) 3 • C 6 H 2 N0 2 , m. p. 130 , which is thus formed, is reduced
