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...
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...
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 ...
1,3,2,4‐Diphosphadiboretanes, 2,4‐bis(dialkylamino)‐Boranes, (dialkylamino)bis(alkylphosphanyl)‐Chromium, pentacarbonyl[2,3‐bis(dialkylamino)1‐1,3,2,4‐diphosphadiboretane] complexesChromium, pentacarbonyl[(2,2,6,6‐tetramethylpiperidino)phosphane‐P]‐...
The molecular structure of the dioxadiboretane 1 and the diselenadiboretane 3 , as determined by X -ray structure analysis, is compared with the structure of the dithiadiboretane 2. All three four-membered ring systems possess a crystallographically imposed center of inversion, and are ...
