以二氯甲烷为溶剂,三乙胺为束酸剂,含吡咯基伯胺2-(2,5-Me_(2)C_(4)H_(2)N)C_(6)H_(4)NH_(2)与氯化物2,6-^(i)Pr_(2)C_(6)H_(3)N C(Cl)C_(6)H_(5)反应以90%的收率得到一种新型邻位苯基桥连中性吡咯基-脒基配体;通过核磁、高分辨质谱、红外光谱对其进行了表征,以无水乙醇为重结晶溶剂,得到了该化合物的单晶,X-射线单晶衍射表明晶体属于三斜晶系,空间群为P,晶胞参数为a=9.2544(10),b=9.5728(11),c=15.8225(17),α=99.7440(10)°,β=97.5900(10)°,γ=96.8580(10)°。该方法对合成含中性吡咯基的多齿配体具有一定的参考价值。

Dichloromethane was used as solvent and triethylamine as bundle acid agent,and a novel o-phenyl-bridged neutral pyrrolyl-amidine ligand was synthesized by the reaction of pyrrolip-amidine 2-(2,5-Me_(2)C_(4)H_(2)N)C_(6)H_(4)NHC(Ph)N(2,6-^(i)Pr_(2)C_(6)H_(3))N=C(Cl)C_(6)H_(5)in 90%yield.It was characterized by NMR,MS and IR technology,taking anhydrous ethanol as recrystallization solvent,and the single crystal of the compound was obtained.The structure was determined to be triclinic crystal system by X-ray diffraction with P as its the space group,a=9.2544(10)as its cell parameter,b=9.5728(11),c=15.8225(17),α=99.7440(10)°,β=97.5900(10)°,andγ=96.8580(10)°.The method has certain reference value for the synthesis of polydentate ligand containing neutral pyrrolyl.
