Synthesis of Compounds of Dichlorodiazabutadiene Structure From Benzoic Aldehyde and Some of Its Derivatives Based on the Catalytic Olefination Reaction

Abstract: Katalitik olefinləşmə reaksiyası əsasında benzoy aldehidi və bəzi törəmələrinin fenilhidrazonlarından dixlordiazabutadien strukturlu birləşmələr sintez edilmişdir. Sintez olunmuş birləşmələrin monokristalları əldə edilmiş və onların molekulyar quruluşları RQA metoduna əsasən təsdiq edilmişdir.RQA tədqiqatları əsasında Cl...Cl qarşılıqlı təsirlərin mövcudluğu və bəzi parametrləri müəyyən edilmişdir. Benzoy aldehidinə elektronakseptor nitro qrupun və flüor atomunun, fenilhidrazinəisə elektrodonor metil qrupların… Show more

“…Schiff bases 1-3 and 7-9 were synthesized according to the reported method. [1][2][3][4] A mixture of (2-nitrophenyl) hydrazine (10.2 mmol), CH3COONa (0.82 g), ethanol (50 mL) and the corresponding 4-substituted aldehyde (10 mmol) was refluxed at 80 °C with stirring for 2 h. The reaction mixture was cooled to room temperature and water (50 mL) was added to give a precipitate of crude product, which was filtered off, washed with diluted ethanol (1:1 with water) and dried under vacuum of a rotary evaporator. (E)-1-(2-nitrobenzylidene)-2-(p-tolyl)hydrazine (1).…”

“…Diazenes 4-6 and 10-12 were synthesized according to the reported method. [1][2][3][4] A 20-mL screw neck vial was charged with DMSO (10 mL), compounds 1-3, and 7-9 (1mmol), respectively, tetramethylethylenediamine (TMEDA) (295 mg, 2.5mmol), CuCl (2 mg, 0.02 mmol) and CCl4 (20 mmol, 10 equiv). After 1-3 hours (until TLC analysis showed complete consumption of the corresponding Schiff base), the reaction mixture was poured into an ~0.01 M solution of HCl (100 mL, ~pH 2-3), and extracted with dichloromethane (3x20 mL).…”
