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...
5. Conclusions In conclusion, our study revealed that treatment with CLP significantly reduced cell migration in the peritonitis model and ameliorated the clinical signs, histopathologic damage, and the production of pro-inflammatory cytokines in the colonic tissue in the colitis model, which is ...
All the expected peaks were still present but more prominently, with the addition of a broad peak in the area of 3450 cm−1 which was assigned to CO–H stretching of acidic head implying on inefficient proton migration to the superbase. In the case of SILCA 11, the formation of amide ...

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 intense bands at 2848 and 2918 cm −1 are assigned to symmetric ν s(CH 2) and asymmetric ν a(CH 2) stretching vibrations of methylene groups. These peaks suggest that the alkyl chains in TOC are nearly in all-trans conformational state. The presence in the infrared spectra of ...
The manganese and iron complexes of the bis-pocket porphyrin (5,10,15,20-tetrakis- (2′4′6′-triphenyl)phenylporphyrin, H2TTPPP) are shown to be shape selective catalysts for the hydroxylation of alkanes and the epoxida...
