With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.94-91-7,N,N’-Bis(salicylidene)-1,2-propanediamine,as a common compound, the synthetic route is as follows.

A mixture of H2salipn (28.2mg, 0.100mmol) and [Ru(PPh3)3Cl2] (95.8mg, 0.100mmol) inTHF (30mL) was refluxed with stirring for 6 h, during which there was a color changefrom brown to dark green. The solvent was evaporated in vacuo, and the residue waswashed with diethyl ether (5mL 2) and hexane (5mL 2). Recrystallization fromCH2Cl2/hexane afforded black block crystals of 11.5CH2Cl2 in 7 days. Yield: 33.4mg,55.6% (based on Ru). IR (KBr disc, cm-1): 1594 (C=N), 1314 (Ar-O); MS (FAB): m/z 679[M], 644 [M – Cl], 417 [M – PPh3]. Anal. Calcd. for C35H31N2O2PClRu1.5(CH2Cl2) (%): C,54.41; H, 4.26; N, 3.48.

Some tips on 94-91-7

As the paragraph descriping shows that 94-91-7 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.94-91-7,N,N’-Bis(salicylidene)-1,2-propanediamine,as a common compound, the synthetic route is as follows.

An ethanolic solution (5mL) of 1,2-diaminopropane (0.109g, 1mmol) was added dropwise to ethanolic solution (10mL) of salicylaldehyde (0.244g, 2mmol) and the resulting mixture was stirred for half an hour. Then, an ethanolic solution (10mL) of iron(III) perchlorate (0.354g, 1mmol) was added under continuous stirring condition and followed by the addition of 5mL ethanolic solution of 4 4?-bipyridine (0.156g, 1mmol). Resulting solution was then allowed to stir for one hour and filtered. Deep brown colored X-ray suitable square shaped crystals were obtained from the filtrate. Yield: 85%. Anal. Calcd. C, 54.74; H, 4.05; N, 9.46. Found: C, 54.73; H, 4.03; N, 9.44; FTIR: nu(C=N)=1614cm-1, nu(skeletal vibration)=1545cm-1, nu(ClO4-)=1087cm1; UV-Vis (methanol): 235, 322 and 509nm.
