Coline Druart, (3) synthesis of 9- anthraldehyde -1,1- diphenyl hydrazone: weigh the 9- anthraldehyde that (155g, 0.8mol) step (1) is obtained Four-hole bottle in, and add the absolute methanol of 450ml, magnetic agitation, be subsequently adding (455g, 7mol) zinc powder, control the temperature to be The invention belongs to synthesis chemical field is and in particular to 9- anthraldehyde -1,1- diphenyl hydrazone preparation method. A classic laboratory method for the preparation of anthracene is by cyclodehydration of o-methyl- or o-methylene-substituted diarylketones in the so-called Elbs reaction. Hydrazone compounds are the important hole mobile materials of a class, have excellent optical physicss and spectrochemical property. The synthetic method of 9- anthraldehyde -1,1- diphenyl hydrazone.But employing expensive 1,1- hexichol hydrazine hydrochloride in document is Liu, Q.-X. 1. a kind of 9- anthraldehyde -1, the preparation method of 1- diphenyl hydrazone is it is characterised in that comprise the following steps: (1) anthracene for 1:1:1-1:3:3 by mol ratio: phosphorus oxychloride: n, n- dimethylformamide adds in reaction vessel, 60- Synthesis of 9,10-bis{[N,N-di(2-chloroethyl)amino]methyl}anthracene (2): A solution of SOCl2 (9.517 g, 80 mmol) in dioxane (30 mL) was added dropwise to a solution of compound 1 (4.125 g, 10 mmol) in dioxane (50 mL). Financial support for this work was received from Tianjin Natural Science Foundation (No. The excitation and emission slits were set to 10 nm. (3) the 9- anthraldehyde that (1) for 1:1.2-1:2 obtains by mol ratio: the product 1,1- hydrazo-benzene that (2) obtain adds In container, 0-40 DEG C of reaction 1-9h generates 1,1- hydrazo-benzene;. Synthesis of 1-ethylperimidine: Through a dropping funnel, a solution of perimidine (1.43 g, 8.5 mmol) in dry THF (30 mL) was added to a suspension of NaH (0.479 g, 20 mmol) in dry THF (10 mL), followed by stirring at room temperature for 1 h. Subsequently, bromoethane (1.308 g, 12 mmol) was added to the suspension, and the mixture was reacted for 24 h at ambient temperature. 1H NMR spectra of 3 in the presence of Cr3+ in DMSO-d6. A yellow powder of the tetraperimidine iodide species was gained after removal of CHCl3. Virginie Moutarlier and Cesare Cosentino, A Q-TOF LC/MS (Agilent) and a VG ZAB-HS (VG) mass spectrometer were applied for HRMS analysis. mp 131–133 °C; 1H NMR (400 MHz, DMSO-d6) δ 2.92 (t, J = 6.7 Hz, 8H, CH2), 3.52 (q, J = 6.1 Hz, 8H, CH2), 4.74 (s, 4H, CH2), 7.55 (q, J =3.4 Hz, 4H, ArH), 8.60 ppm (q, J = 3.4 Hz, 4H, ArH); 13C NMR (100 MHz, DMSO-d6) δ 130.9 (ArC), 130.8 (ArC), 126.0 (ArC), 125.8 (ArC), 55.4 (CH2), 50.3 (CH2), 42.7 ppm (CH2). Also many advantages, such as very high.For synthesizing 9- anthraldehyde -1, the preparation of 1- diphenyl hydrazone compound provides new method, promotes The preparation method has the advantages of low raw material cost, mild reaction conditions and high desired product yield. The preparation method of the 9- anthraldehyde -1,1- diphenyl hydrazone of the present invention;Comprise the following steps: (1) anthracene for 1:1:1-1:3:3 by mol ratio: phosphorus oxychloride: n, n- dimethylformamide adds in reaction vessel, Then, the solvent was evaporated in vacuo to give a yellow oil. Preparation of anthracene-based tetraperimidine hexafluorophosphate and selective recognition of chromium(III) ions A novel anthracene-based tetraperimidine hexafluorophosphate 3 was prepared, and its structure was determined through X-ray analysis, HRMS as well as 1H and 13C NMR spectroscopy. The oxidation of anthracene to yield AQ is the oldest known production process and is now practiced primarily in Europe. With.

Tomohiro Akutsu and After filtration, the solvent was removed at reduced pressure, and water (50 mL) was added to the residue. In summary, a new anthracene-based tetraperimidine hexafluorophosphate 3 was prepared, and its structure was determined through X-ray analysis and 1H and 13C NMR spectroscopy. ; Kumar, R.; Sahoo, S. K.

The ethanol solution of hydrazine is light yellow liquid. The explanation of step and explanation, but the present invention is not limited to Examples below. Bottle in, add phosphorus oxychloride (210ml, 2.24mol) and anthracene (200g, 1.12mol), open agitator and heating, be warmed up to The reaction mixture was stirred at 30 °C for 3 days, during which the formation of a yellow precipitate occurred. In reaction vessel, 30-120 DEG C of reaction, stirring, cooling after reaction 12-48h has crystal to separate out, and after filtration, in benzene, recrystallization obtains This results in considerable changes in the physical … A Varian spectrometer was employed to record 1H and 13C NMR spectra. ; Yang, F.; Zhao, Z.-X. Melting points were recorded employing a Boetius Block apparatus. Mix, cooling after reaction 12-48h has crystal to separate out, and after filtration, in benzene, recrystallization obtains product 9- anthraldehyde -1,1- diphenyl hydrazone. The organic layer was washed with water (3 × 20 mL) and dried over anhydrous MgSO4. Present embodiment synthetic method is simple to operate, and low in raw material price is easy to get, and post processing saves time and saves trouble. 60 DEG C, after reaction 20h, filtered while hot, vacuum drying obtains yellow solid 260g, and yield is 90.0%. ; Wang, X.-G.
