The separation capacity of a TLC method can be easily improved by use of a two-dimensional high performance TLC technique (2D HPTLC). Various plant essential oils (menthae, thymi, anisi, lavandulae, etc.) have been analysed by 2D TLC with florisil (magnesium silicate) as the adsorbent, using dichloromethane/ -heptane (4 6) in the first direction and ethyl acetate/n-heptane (1 9) in the second direction (69). 

Tetra-/>-anisy lhy drazine is green in benzene at room temperature.185 On the other hand, 1,2-diphenyl-1,2-di- >-nitrophenylhydrazine appears not to be dissociated at all. If this difference in degree of dissociation is real, and not a specious one due merely to a difference in color or reactivity of the radicals, it presents a puzzling contrast to the case of diphenylpicrylhydrazyl and to the triphenylmethyl series in which both kinds of substituent stabilize the radical. 

Protonation of ( -l-/ -anisyl-2-(triisopropylsilyl)ethene 17 with FS03H in S02C1F/S02F2 yields a mixture of syn- and anti -p-anisy -2-(triisopropylsilyl)ethyl cations 18 (13, 21).

The same dilution technique is usually applied in the analysis of ethereal oils [210]. It can be used in the determination of aldehydes such as citral and citronellal in lemon oil (Oleum citri) and in Oleum verbenae, of anisaldehyde in Oleum anisi stellati. Oleum anisi and Oleum foeniculi, of cinnamaldehyde in Oleum cinnamomi, and of ketones, such as car-vone, in Oleum anethi, of pulegone and diosphenol. In all these cases, the oil is first diluted with ethanol and to this solution an aqueous solution of the supporting electrolyte is added, usually only 0.1 M LiCl. 

Di-anisidine.—A derivative of di-phenyl which is related to benzidine, and related also to anisole, CeHs—OCH3 (p. 612) and to anisi-dine, H2N—CeH4—OCH3, is known as di-anisidine. 

Diphenyl-1,2-dithiolium ion leads to 3-amino-1,3-diphenylprop-2-ene-l-thiones when reacted with methylamine, ethylamine, ben-zylamine, 2-aminoethanethiol, piperidine,aniline, toluidines, anisi-dines, and chloranilines. With dimethylamine a double condensation, analogous to the one shown in Eq. (15), occurs. ... 

Conformational factors can determine more than the stereochemistry of rearrangement. In light of Collins findings, let us examine work done earlier by D. Y. Curtin (of the University of Illinois) with 2-amino-1-anisy 1-1-phenyl-1-propanol. This resembles Collins labeled compound (p. 899), except that an anisyl group (p-methoxyphenyl group) takes the place of one of the phenyls. Here, the competition in migration is between a phenyl and an anisyl, instead of between labeled and unlabeled phenyl groups.

Since 2005, the Eur. Pharm. has changed its monograph for Anisi aetheroleum by limiting the source of the oil to Pimpinella anisum L. (formerly P. anisum and Illicium vemm Hook). In general, the monograph conforms with the ISO standard, supplemented by the limitation for foeniculin (max. 0.01%, adulteration with star anise oil) and fenchone (max. 0.01%, mixing or adulteration with fennel oil).
