(Roche) was also used in place of glutamyl-tRNA in a separated assay. LC-MS analysis of the above reaction mixtures after Fmoc chloride (Fmoc-Cl) derivatization, revealed that they both generated a new product with the same retention time and mass signal (m/z514, [M + H]+ion) ...
1,1,1-Trichlorotrifluoroethane [94] Hexachloro-1,3-butadiene [61] 1,1,1,2-Tetrachloroethane [61] Perfluoro-2-methyl-2-pentene [95] Perfluorohexane [95] 1H, 1H, 2H, 2H - Heptadecafluorodecyl acrylate (HDFDA) [96] 1H,1H,2H-Perfluoro-1-decene (HDFD) [97] First efforts were from ...
α-Aminoboranes have generally been synthesized by reactions between anitrogen ylideand a trialkyl- or triarylborane. Muster and Stevens<1967TL995>first described the reaction of an unstabilizedN-ylide with boranes (Scheme 41). The presumed initial zwitterionic borohydride intermediate121rapidly underw...
Phenylhydrazine (0.551 mL, 5.6 mmol) was added to a solution of N-(2,6-dimethyl-phenyl)-2,2,2-trifluoro-acetimidoyl chloride (263.4 mg, 1.12 mmol) (prepared from TFA, 2,6-dimethyl aniline, Ph3P, CCl4, and Et3N according to the procedure of Tamura, K., et al., J. Org. Chem. ...
A series of manganese complexes bearing an anionic pyrrole-based PNP-type pincer ligand and an anionic benzene-based PCP-type pincer ligand is synthesized and characterized. The reactivity of these complexes toward ammonia formation and silylamine format
When the reaction mixture was poured into the ammonium chloride solution, the excess KCN neutralized the ammonium cation to form free ammonia, which then quickly displaced a second dimethylpyrazolyl fragment with the formation of 3-amino-6-cyano derivative 1 (Scheme 1). From the technological ...
1,2,6-Thiadiazine ring may be constructed from enaminoimino derivatives as it was shown by the reaction of 3-(1-amino-2,2,2-trifluoroethyliden)-1,1,4,5,6,7-hexafluoro-2-iminoindane 51 with thionyl chloride (Scheme 27) [170]. Scheme 27. Synthesis of fluorinated dihydroindeno[2,1-...
