AN Latv.SSR, 1957, 13, 217-225 Abstract : Two phases of inhibition in the development of parabiotic process were discovered: I - electro-positive, in which the inhibition of excitability and condL,.ctivity is con- nected with the increase of functional mobility, and II - electro-negative, which is characterized by progressing decrease of lability.

In thirteen tests done on the preparation from sensitized frogs, seven showed a noticeable drop in the level of the curve on the threshold parablocis (ICTF) when it was put on the cathode part of the nerve.

Consequently, the local anaphylactic effect of S on the nerve was added to the parabiotic effect of the cathode. The lowering of LCTP was also obtained when S was applied to the exposed interstitial brain. In a series of teats, the threshold cathode parabiosis was produced in the part of the nerve which was connected both to the mu3cles and to the brain. In =at of these tests done on sinsitized frogs, after the administration of decisive dooea of S there occurred a sufficiently well expressed lowering of the LCTP. In this way, in all the described cases the parabiotic state of the nerve part, produced and kept at the threshold level, becaly, deepened. -- F. 1. tvaimladze Card 2/2 115 WSIL-YILV, L. L.

The principle su--ested in this paiur is based upon the use of a stereocoiriparator which permits differential motions of the film holders parallel to the principal axes of the device. These supports are moved by electrical motors of a servo-system., aliich are connected with an electrical computer. This Computer takes into account the running point coordinates, and continually calculates the corrections during trans- for-,ations and transforms them to mechanical displace~7,ents of the servo-system. Soviet scientists have worked out a method for determining, the relation between the coordi- Card 1,13 nates obtained from tilted and horizontal photographs A Stereocomparator With Electromechanical Correction S0111154-58-5-15118 through corrections to the cardinal focal length, which considerably simplifies the structure of the formulae (no transcendent functions). If nuch a new type of corrective device in used, the photographs can be trans- formed to a case of normal exposure. The transformed values of the coordinates obtained with thin device are then used in the computation of points of the terrain according to very simple formulae. Such a type of equipment serves for the determination of a limited number of points. This paper describes the particular features of the theory of the interpretation of photographs in a rectangular frame of reference, this theory being taken account of in the development of the principal lay-out of this device. An the method presented of space intersecting is based upon the work of Professor F. V. Drobyshev and Professor G. V. Romanovskiy a presentation of the basic lines of t)- theory for this instrument due to these authors is included in this paper.

Both compounds were then hydroboronated with diborane. The experimental procedure is detailed. The results indicate that fraction C8H15B is almost entirely in the form of V11. This is attributed to the verified much faster rate of hydroboronation for V than V11. Participation of the two compounds in the formation of isomeric butanediols during the oxida- tion of product mix resulting from hydroboronation of butadiene-1, 3 was 78% for V and 22% for VIL A schematic representation of the process of mono-hydroboronation, given in the report, negates assumptions by H.

M. Mikhaylov, A. A. Akhnazaryan, L. S, Vasillyev, Dokl. AN SSSR 156, 828, 1961). Tetraalkyl diboranes were found to react with orthoborates slowly at room temperature and quickly when heated (800-10000), giving alkyl boric acid esters (80-90 % yield R B H + 2(R'0) B - 3RB(OR'~- 1/2 R B H 4 2 2 3 2 2 2 4 R - n-C 3H, n - C 4H9; R'= CH 39 n-C3H 71n C7H15' Reaction 1.) proceeds via several stages, alkyl and alkoxyl groups being subgtituted for the hydrogen in tetraalkyl boranes and their primary Card 1/2 209a5 S/062/61/0-~0/003/012/0';~ New method of synthesizing alkyl...

TITLEs Synthesig and Proportion of Totra-n-propyl Diborane and Tetra-n-butyl Diborane PERIODICAL3 Doklady Akademii nauk SSSR, 1961j Vol. 1)6, No- 4, pp. 828 - 831 TEM The authors studied the reaction of diborane with tri-n-propyl boron and tri-n-butyl boron in otheric solution, and determined the following factes 1) When passing 1 mole of diborane through a 4-mole solution of boron trialkyl at room temperature, tetraalkyl diboranes are produced in a yield of 70-85%, i.e., tetra-n-propyl or tetra-n-butyl diborEne. 2) When using an equimolecular quantity of diborans, an asyametric di-n-propyl diborane is isolated by distilling the reaction products. The second synthesis method is based on the reaction between diborane and olefins (Ref-4). This reaction is catalyzed by different others. Reaction 8f diborane with propylene-1 and butene-1 (ratio 1 A 4) at -70 to -30 C in an etheric medium resulted in a 46% yield of tetraalkyl diboranes. The latter Card 1/3 88406 Synthesis and Properties of Tetr&-n-propyl 8/020/61/136/004/014/026 Diborane and Tetra-n-butyl Diborane B016/BO75 are completely stable up to 100 0C and can be distilled in vacuo. In benzene solution they are partly dissociated into dialkyl borane. Tetra- alkyl diboranes spontaneously inflame in the open air. They are highly reactive and react with alcohols under the formation of dialkyl borio acid esters. With aniline they form dialkyl phonyl amino boron. Under the action of mercaptans, tetraalkyl diboranes are converted to dialkylthio- boric acid. Such reactions are convenient preparation methods for synthesizing organoboron compounds, since only small quantities of side- products are formed. Tetra-n-butyl diboranes more difficultly react with glycol. In this came, almost equal quantities of glycol esters of di-n- butyl boron and n-butyl boric acid are formed, and, in addition, tri-n- butyl boron. From the formation of the latter, the following was con- oludeds The action of nuoleophilic reagents causes a substitution of hydrogen atoms by tetraalkyl diboranes, and also a disproportionstion of tetraalkyl diboranes into boron trialkyls and alkyl boranes. Under the action of a nucleophilic reagent, the alkyl borans thus forming results in an organoborot compound with a radical on the boron atom. On the other hand, boron trialkyl remains either unchanged (e.g., in the rtaotion with glycol), or enters into reaction and, e.g., with marcaptan, forms an Card 2/3 88406 Synthesis and Proportion of Tetra-n-propyl S/020J61/136/004/014/026 Diborane and Tetra-n-butyl Diborane B016/BO75 ester of dialkyl thioborio acid (Ref.6).
