ABSTRACT: In order to investigate systematically the relation between
the scintillating properties and the structure of the oxadi-
azole derivatives the authors synthesized the following hither-
to unknown derivatives of 2,5-diphenyl-1,3,4-oxadiazole with
different functional substituents which are in the para-
position of one of the phenyl cycles:
N-11
R NO2, NH 21 NHCOCH 3' OH, OCH3
OCOCH 3' Cl, Er, J.
The synthesis of such compounds usually takes place according
to. the general scheme (I) for the compounds of this type; in
Card 1/3 the case of the oxadiazole derivatives, however, in which the

functional groups (like the amino and the oxy group) may re--
act by themselves with the reagents to be used , it cannot be
employed. Therefore, in such cases, scheme (2) hitherto not
applied for the synthesis of similar compounds was used. In
this scheme (2) the stage of the reduction of the nitro group
to the amino group and their substitution by other functional
substituents is of interest. Since, as had been found earl-Jerg
the oxadiazole ring is sensitive to the action of aqueous
mineral acid and alkali solution and,espec--ally at high tempera-
tures, decomposes f4~,.=st into the corresponding hydrazide and
then into the hydrazine and aromatic acids, it was no'. possfbls
to obtain in sufficient yield 2-phenyl-5-(4-aminophenyl)-
1,3,4 oxadiazole by the reduction of the corresponding oxa-
diazolle derivative in acid and alkaline medium. Only pheny-1
hydrazine used as reducing agent produced good yields. The
amino group which is in para-position, in the 2,5-diphenyl-
1,3,4-oxadiazole is very reactive, and thus Dermitted the syn-
thesis of many derivatives of 1,3,4-oxadiazcle important with
respect to scintillation. 9 hitherto unknown p-substituted

TEXT: Basing on their earlier papers (Refs. 1-6) concerning the synthesis
of scintillation substances, the authors in the present work describe the
synthesis of new functionally substituted compounds of this type. The fol-
lowing scheme, described in Refs. 2 and 8, was applied for the prepara-
tion of para-substituted 2,5-diphenyl 1,3,4-oxadiazoles with the substitu-
ents F,SCH 3CH 3, iso-OC3H79 N(CH 3)2T COOH, and COOC2H 5:

of isomeric monofunctional 2,5-diphenyl 1,3,4-oxadiazole derivatives. In
this way, the authors obtained the first representatives of ortho- and
meta-substituted oxadiazoles with nitro, chlorine, methoxy, and methyl
groups as substituents. The reaction conditions and yields did not differ
significantly from those of the para-substituted oxadiazoles. This method
is therefore generally applicable for the preparation of functional oxa-
diazole derivatives and the diaroyl hydrazides used as initial compounds.
Contrary to published data (Ref. 8), the diaroyl hydrazides form at low
temperatures also, higher temperatures causing formation of considerable
quantities of by-products, i.e. symmetric diaroyl hydrazides of the types
(C6H 5- CON H)2 and (X_C6H4_ CONH) 29 especially in presence of electrophilic
substituents in the phenyl ring, such as NO 2 and COOC 2 H5 (Refs. 8 and 9).
The application of scheme (1) may be complicated by reaction of the func-
tional group with the reactants. This can be avoided, however, by trans-
forming the functional substituent of the oxadiazole molecule into another
group, i.e. reduction to amines, Sandmeyer reaction, conversion of nitrile
to amide (Ref. 10). Saponification of the ester group in 2-(p-carbethoxy

acid, however, was accompanied by oxadiazole ring cleavage, which led to
the formation of 1-(p-carbethoxy benzoyl) 2-benzoyl hydrazine. On treat-
ment with phosphorus oxychloride, the latter forms compound (I), which
cyclizises with H 20. Table 1 gives a list of the diaroyl hydrazines

ABSTRACT: This decoder converts (decodes) an n-place NI-th number successively In time,
beginning with the most significant and endingwIth the least significant digit, Into a single-dIgit
number having a certain number of signs. Decoder configuration Is thus a tree of a certain
degree of complexity, in which each branching (selection) node, Including the first, has a num-1
ber of branches which equals the number of signs In the given digital place. The speed of
response of this decoder ajid the amount of current which It can deliver to the final control
element, as well as the minimum cur-rent needed for switching the diodes of all degrees of
selection, not including the last, are determined by the type of switching diode used In the
circuit. This decoder may be used both with die unIpolar circuit described In the article and

with a dipolar one. In the latter case the number of switching diodes and resistors in the firing
circuits is reduced almost by half. This decoder may be partially used in conjunction With
other types of contactless decoders of both pulse and voltage types. In this case the switching
diodes and the methods of turning them on may be used in several selection stages, but prefer-
ably In just the final one. Operation of two circuits is described in detail. Orig. art. has: 6
