Study On The Preparation Of Replace The Etylenediamine Metal Complexes And Their Application In The Synthesies Of Benzene Ac-Etonitrile

Schiff bases are a class of organic compounds mainly refers to containing imineor methylene amine groups （RC=N-）. Schiff bases are usually synthesiced by amineand carbonyl condensation. Based on preliminary instead of ethylenedi-amine,1,3-propylene amide to produce schiff bases, then schiff bases were reduced to amine, andamides were combined with Cu（AcO）₂to form copper complexes. The copper complex-es as catalyst, K4[Fe（CN_）6] as cyanating reagent to the general synthesis of aryl nitrilesfrom aryl cloromides. The cyanation reaction was studied.1. The synthetical methods of instead of ethylenediamine metal complexes andtheir application in the synthesis of aryl nitriles were reviewed.2. Aniline and its derivatives reacted with oxalyl chloride to produce amides.Then amides were reduced by LiAlH₄or NaBH₄-I₂to prepare N, N ’-diphenyl ethylenediamine compounds.3. Aromatic aldehyde compounds reacted with ethylenediamine and1,3-propane-diamine respectively to directly synthetize imines. Then the imines were reduced byNaBH₄or KBH₄to amines.4. Aromatic aldehyde reacted with ethylenediamine and1,3-propane-diaminerespectively to generate corresponding imides under the case of anhydrous MgSO₄andCH₂Cl₂. Then the imides were reduced to amines under the action of NaBH₄andCH3OH.5. Aldehyde compounds were directly reacted with diamine to give and amidesunder the I₂/TBHP system and then amides were reduced by NaBH₄or KBH₄to theamines. 6. The prepared amines were reacted with Cu（AcO）₂to form Copper complexes.7. With the synthetized ethylenediamine Copper complexes as catalyst,K₄[Fe（CN）₆] as cyanating reagent to synthesis of aryl nitriles from aryl cloromides.8. The parts structures of intermediates and target products were characterized by¹H NMR and¹³CNMR spectra and combined with gas chromatography to evaluate theresult of the catalytic reaction.
