A modular approach for the synthesis of planar π-extended selenium containing mols. from selenophene has been developed. Different combinations of Pd-catalyzed desulfitative C-H bond arylations with (2-bromo)arylsulfonyl chlorides R-2-BrC6H3SO2Cl (R = H, 4-CF3, 4-F, 5-CF3) and Pd-catalyzed intra- or/and inter-mol. C-H bond arylations with aryl bromides R1Br (R1 = 4-CNC6H4, 5-acetylthiophen-2-yl, 3-F3CC6H4, etc.) allowed the extension of the selenophene-containing aromatic skeleton at the [b]-, [c]- or [b:d]-junctions to give phenanthro[b]selenophenes, e.g. I, phenanthro[c]selenophenes, II (R2 = CN, NO2, OCH3, CF3; R3 = H, CF3) or diphenanthro[b:d]selenophenes III (R4 = H, CF3, CN; R5 = H, CF3). In the experimental materials used by the author, we found 2-Bromobenzonitrile(cas: 2042-37-7HPLC of Formula: 2042-37-7)
2-Bromobenzonitrile(cas: 2042-37-7) belongs to a group of ortho-substituted bromobenzenes that have varying hepatotoxicity effects in the presence of rat liver microsomes in vitro. 2-Bromobenzonitrile is also used as a starting material to synthesize novel benzothiophene derivatives that were found to exhibit antibacterial and antifungal activity.HPLC of Formula: 2042-37-7
