Salts of the Bis(diisopropylamino)boron(1+) Cation Bromobis(diisopropylamino)borane ( 1 ) reacts with aluminium and gallium tribromide to produce stable salts of type [( i Pr 2 N) 2 B]EBr 4 ( 2 , 3 ). Silver triflate converts 1 into bis(diisopropylamino)[(trifluoromethyl)sulfonyl...
The polymer gave qualitative tests for peroxide, but iodimetric titration of one sample gave only some 42.5% of the calculated active oxygen content.doi:10.1002/pol.1948.120030406V. GutmannJournal of Polymer Science
Tetramethyltitan wird von einem Überschuß an N,N′-Bis(trimethylsilyl)benzamidin (1) zum Bis[N,N′-bis(trimethylsilyl)benzamidinato]dimethyltitan (2) protolysiert. Diese Verbindung konnte isoliert und ihre Kristallstruktur ermittelt werden. Danach liegt 2 im Kristall in oktaedrischer Ko...
R e s u m e n : En esta ocasion fueron comunicados diferentes resultadas, los cuales fueron alcanzados con el aqui empleado método de agua oxigenada. Partiendo de la demonstracion de que existe una distinta reaccion entre la potenciacion por medio de progresiva disdlucion con ...

The exchange of substituents between 3,5-dibromo-1,2,4,3,5-trithiadiborolane ( 1 ) and 1,2,3-trimethyl-1,3,2-diazaborolidine ( 2 ) proceeds via formation of adducts as indicated by tetracoordinated boron atoms but definite products could not be isolated. However, a well defined ...

Isothiazoles with diazonium groups in 3-, 4- or 5-position ( 1, 6, 9 ) were prepared and isolated. The compounds showed significant differences in their behavior toward nucleophilic agents and in their coupling power. The difference between the behavior of 3-isothiazol-diazonium salts and ...
