AN SSSR-101/2,-265-2681 Mar Up 1955 Abstract I A study of the acylation reaction kinetics of biphenyl amino derivatives showed thatthe reaction between the N02 and NH2 groups 4,41 positions is considerably weakened if t e interfial rotation of the aromatic nuclei in the molecule is retarded by the introduction of 2,21-alkyl sub- stitutes. The steric effect of 2,21-carbomethoxyl groups on.the reactivity of 4-amino-41nitrobiphenyl was investigated. The results obtained are des-_ .cribed. Nine references: 3 USSR and 6 USA (1934-1954).

Table 2 gives results at 25 C and 50 C for the first compound and Table 1 values for tl,-.e second compound at tile same temperatures. On comparing the velocities of acylation of the 2 compounds it can be seen that the carboisopropoxyl groups possess clearly defined electro-acceptor character as the velocity constant dur- irg the transition from one compound to the second com- pound decreases to half its value.

ABSTRACT: In order to establish the relation between spatial configuration and reactivity in bi-nudear aromatic amino-nitm derivatives, comparative studies were made on the kinetics of acylation reaction for 4-aminobiphenyl and 4-amino-4'nitrobiphenyl on one hand and derivatives of these amines containing various substitutes in 2,21-positions on the other hard. It was shown that an increase in the angle between the surfaces of benzene rings during the change from 4-amino-4-nitrobiphenyl to its 2,21-derivatives is due to the steric hindrances between 2,21-substituents leading to a considerable weakening of the reaction of the N02- and NH2- groups oriented in 4,41-positions of the molecules Qf the compounds Card 1/2 indicated. It was found that the fluorene system being iwre planar Spatial Structure ard Reactivity 483 than the biphenyl system is a much better transmitter of electronic effects of the substituents. Attention is called to the fact that 2-aminofluorene is similar by its kinetic parameters to its very close analogue 4-amino-2,21-dimethylbephenyl whereas 2-amino-7 nitrofluorene differs from its analogue - 4-amino-41-nitro-2,21-, dimethylbiphenyl by its energy and activation entropy values. Thi kinetic acylation data for 2-amino-7-nitrofluorene are in many respects analogous to the kinetic data of 4-amino-41-nitrobiphenyl, Four tables. There are 16 references, of which 10 are Slavic.

PERIODICAL: Zhurnal Obshchey Khimii, 1957, Vol. 27, Nr 11, PP. 3115-3122 (USSR) ABSTRACT: For kinetic investigations performed In the laboratory 2,21-dimetoxyl- and 3,31-dimethyl-derivatives of 4-aminodiphenyl and 4-amino-4'nitrodiphenyl had to be made available. It was found that the synthesis of the metoxyl- derivatives is most expediently to be realized according to scheme 1 (see formulae). The easily accessible o-tolidine served as starting product for the synthesis of the methyl derivatives. Their synthesis is represented by scheme 2 (see formulae).

Each Gubatanco was purified by recrystallization from solution and chromatography on aluminium oxide. The authors measured the relative intensity and photoluminescence spectra and the integral scintillation yield in toluene and polystyrene solutions of various concentrations. The absorption and luminescence spectra of AM, LNBD and PBD in heptane were also measured. The spectra and intensities of luminescence were measured by means of a SF-4 spectr o photometer, used as a monochromator and a photomultiplier FEU-18. A mirror galvanometer M-21 was used to record the photo-current. The integral scintillation yield was determined from the choto-currant of a FEU-19 ohotomultiplier to whose window a radioactive AS110 source (0.1 millicurias .) ~%us fixed. The absorption s-jectra were measured by means of a SF-4 spoctrophotomotar. The ro3ults are given in Figs 1-11. The concentration dependences of the intensity of photoluminescence and of the scintillation efficiency vere similar for all the three substances in polystyrene (Figs 1-5). In toluene solutions MtPPD shows a stronger concentr,).tion quenching of luminescence (Fig 4) than the other two substances (Figs 5 and 6).

In order to investigate the dependence of the structure on the scintillation activity in the series of the oxadiazole derivatives and to find new compounds very active in this respect, the authors synthesized the asymmetrical 295-diaryl substituted 1,3,4-oxadiazoles which have not yet been described in publications. The hydrazides corresponding to them were also new.

In the first stage the formation of the asymmetric hydrazide in pyridine may be complicated by the fact that besides the main product sometimes also the symmetric hydrazide is obtained. In the second stage a short heating of the corresponding diaryl hydrazide with POM 3 only until its complete dissolution is sufficient for the formation of the oxydiazole ring. A further heating leads to a deterioration of the product. All hydrazides synthesized are colorless crystalline compounds. The following compounds were newly synthesized: 2-phenyl-5-~I-naphthyl), 2-0-biphenylyl-5-0-naphthyl-, 2-pbonyl-5-(2-naphthyl)-, 2-(4-biphenylyl)5-(2-naphthyl)-, Card 2/3 and 2-(I-naphthyl)-5-(2-naphthyl)-1,3,4-oxadiazole as well as Synthesis of the Asymmetric 2,5-Diaryl Derivatives SOV/79-29-6-49/72 of lv3v4-Oxadiazole their hydrazides.
