二安替比林甲烷芳环衍生物的合成及其光度性质的研究

Study on synthesis of DAPM and its aromatic derivatives and their spectrophotometric properties

合成了DAPVM,DA-o-CM,DA-m-CM,DASM,DADMM,DAPM,DAMAM,DANM,DAHMM等9个二安替比林甲烷芳香族衍生物,其中DA-o-CM和DA-m-CM为首次合成。研究了在 H_3PO_4介质中和Mn(Ⅱ)存在下其与Cr(Ⅵ)、V(V)、Ce(Ⅳ)的显色反应。开发了几个试剂的应用体系,显示了良好的应用前景。

Nine derivatives of diantipyrylmethane were syn-thesized.They are diantipyrylphenylvinylmethane(DAPVM),diantipyryl-o-chlorophenylmethane(DA-o-CM),diantipyryl-m-chlorophenylmethane(DA-m-CM),diantipyrylsalicylmethane(DASM),diantipyryl-3,4-dimethoxyphenylmethane(DADMM),di-antipyrylphenyl methane(DAPM),diantipyryl-p-dimethylaminophenyl methane(DAMAM),di-antipyryl-m-nitrophenyl methane(DANM)and di-antipyryl-3-hydroxy-4-methoxyphenylmethane(DAH-MM).DA-o-CM and DA-m-CM were synthesized forthe first time.The color reactions of the above men-tioned reagents with Ce(Ⅳ),V(Ⅴ),Cr(Ⅵ)in thepresence of H_3PO_4 and Mn(Ⅱ)were stud-ied.Applications of some of these systems were pro-posed.These methods appear to have a bright future.
