And the article was included in Turkish Journal of Chemistry in 2009.Product Details of 697-73-4 This article mentions the following:

Starting from (5-nitrofuran-2-yl)methylene diacetate, a series of 2-[(substituted benzyl)thio]-5-(5-nitro-2-furyl)-1,3,4-thiadiazoles were synthesized and characterized. The in vitro anti-Helicobacter pylori activity of the synthesized compounds was evaluated by the disk diffusion method against the clin. isolates of Helicobacter pylori. The results indicated that most of the synthesized compounds exhibited significant inhibitory activity against H. pylori with respect to standard drug metronidazole. Compound I, containing the 2-chloro-6-fluorobenzylthio moiety, was the most potent compound tested. In the experiment, the researchers used many compounds, for example, 2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4Product Details of 697-73-4).

2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4) belongs to organic chlorides.

Synthesis of quinolines via ortho-lithiated N-acylanilines. A modified Friedlaender synthesis was written by Cho, In Seop;Gong, Leyi;Muchowski, Joseph M.. And the article was included in Journal of Organic Chemistry in 1991.Quality Control of tert-Butyl (4-chlorophenyl)carbamate This article mentions the following:

A new variation of the Friedlaender quinoline synthesis was devised based on the sequential reaction of ortho-lithiated N–tert-Boc-anilines or N-pivaloylanilines with masked malondialdehyde derivatives, e.g., vinamidinium salts I (R = H, Ph), 3-(dimethylamino)acrolein, and 3-ethoxymethacrolein, and subsequent acid-induced cyclization. Thus, anilines II (R¹ = H, F, Cl, Me, OMe, R² = OCMe₃) were lithiated and cyclized with I (R = H) to give quinolines III. Lithiation of II (R¹ = F, R² = CMe₃) and cyclization with EtOCH:CMeCHO gave III (R¹ = F, R = Me). In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Quality Control of tert-Butyl (4-chlorophenyl)carbamate).

The coordination chem. of a bidentate ambiphilic ligand, PhB(CH₂P^tBu₂)₂ ([BP₂^tBu]), is established for a series of Co, Ni, and Cu compounds The chloride starting materials [BP₂^tBu]MCl₂ [M = Co (1_Co), Ni (1_Ni)] and [BP₂^tBu]CuCl (2_Cu) are readily accessed in high yields by the treatment of the corresponding metal chloride salts with [BP₂^tBu] in THF solution The reduction of 1_Ni to [BP₂^tBu]NiCl (2_Ni) was affected by treatment with KC₈. In contrast, the corresponding Co^I species was not isolable under similar reaction conditions. However, monovalent mesityl complexes of the form [BP₂^tBu]M(Mes) [M = Co (3_Co), Ni (3_Ni), Cu (3_Cu)] were prepared by the treatment of 1_Co with one equiv of Mes₂Mg(THF)₂ or by the reaction of 2_M (M = Ni, Cu) with 0.5 equiv of Mes₂Mg(THF)₂. Modification of the borane moiety in 2_Ni was explored by the treatment of this complex with 4-dimethylaminopyridine (DMAP) to produce [PhB(DMAP)(CH₂P^tBu₂)₂]NiCl (4), which displays distinct features in its UV-visible spectrum compared to 2_Ni. The solid-state mol. structures of most complexes have been determined by single-crystal X-ray diffraction anal.
