【Abstract】 1,2-Bis( 2’-methoxyphenoxy) ethane( 1) was synthesized through substitution reaction,using 2-methoxyphenol and 1,2-dibromoethane as starting materials.The crystal structure was studied,which is an important intermediate in the synthesis of open chain polyether compounds.The potassium salt of 2-methoxyphenol phenol was obtained by potassium hydroxide and 2-methoxyphenol.The total yield was 92. 2%. The compound was characterized by1 H NMR,13 C NMR,ESI-MS and IR. The crystal structure was determined by X-ray single crystal diffraction method.The crystal belongs to monoclinic system with space group P21/ n,a = 7. 448( 2) ,b= 5. 0320( 16) ,c= 18. 693( 6) ,β= 92. 575( 8) °,V = 699. 9( 4) 3,Z = 2,Dc= 1. 302 g / cm3,F( 000) = 292,μ = 0. 093mm-1,R= 0. 0590,wR= 0. 1324( I>2σ( I)).更多还原
