Synthesis of quinoline-based NNN-pincer nickel(II) Complexes: a robust and improved catalyst system for C-H bond alkylation of azoles with alkyl halides was written by Patel, Ulhas N.;Pandey, Dilip K.;Gonnade, Rajesh G.;Punji, Benudhar. And the article was included in Organometallics in 2016.HPLC of Formula: 57293-19-3 This article mentions the following:
The quinoline-based pincer nickel(II) complexes I (2a,b, X = Cl, R = Me, Et; 3a,b, X = Br, R = Me, Et; 4a, X = OAc, R = Me) were prepared by the reaction of the ligand precursors N-[(2-dialkylamino)phenyl]-8-quinolinamines with (DME)NiCl2 (THF)2NiBr2 or Ni(OAc)2 in the presence of Et3N. All of these complexes were characterized by 1H and 13C NMR spectroscopy as well as by elemental anal. Further, the mol. structures of 2a and 3a,b were elucidated by x-ray crystallog. Complex 2a is found to be an efficient catalyst for the direct C-H bond alkylation of substituted benzothiazoles and oxazoles in 2-position with various unactivated alkyl halides containing 灏?hydrogens under mild reaction conditions. The catalyst 2a is very robust and was recycled and reused five times for the alkylation reaction without a decrease in its catalytic activity. Preliminary studies reveal that the catalyst 2a acts as an active catalyst and the alkylation reaction appears to operate via a radical pathway. In the experiment, the researchers used many compounds, for example, 1-(3-Bromopropyl)-4-methoxybenzene (cas: 57293-19-3HPLC of Formula: 57293-19-3).
1-(3-Bromopropyl)-4-methoxybenzene (cas: 57293-19-3) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.HPLC of Formula: 57293-19-3
