Wei, Wen; Yu, Hao; Zangarelli, Agnese; Ackermann, Lutz published the artcile< Deaminative meta-C-H alkylation by ruthenium(II) catalysis>, COA of Formula: C9H7BrN2, the main research area is alkyl arene preparation chemoselective regioselective; heteroarene Katritzky pyridinium salt deaminative alkylation ruthenium catalyst.
A ruthenium-catalyzed meta-C-H deaminative alkylation with easily accessible amino acid-derived Katritzky pyridinium salts I (R = H, CO2Me, N-[(2S)-1-methoxy-1-oxopropan-2-yl]carbamoyl; R1 = CO2CH2CH3, CH2C6H5, 1H-indol-3-ylmethyl, etc.) has been described. Likewise, remote C-H benzylations were accomplished with high levels of chemoselectivity and remarkable functional group tolerance. The meta-C-H activation approach combined with the deaminative strategy represents a rare example of selectively converting C(sp3)-N bonds into C(sp3)-C(sp2) bonds.
Chemical Science published new progress about Alkylation catalysts, regioselective (deaminative, chemoselective). 13788-92-6 belongs to class pyrazoles-derivatives, and the molecular formula is C9H7BrN2, COA of Formula: C9H7BrN2.
