2-(2′-苯基丙烯基)苯并噁唑类化合物的合成及晶体结构

Research on Substituted 2-(2'-Phenylpropenyl) Benzoxazoles

合成了11种2-(2′-苯基丙烯基)苯并噁唑类和9种2-(2′-苯基丙烯基)-5-甲基苯并噁唑类化合物。测定了它们的熔点、元素分析、红外光谱及个别衍生物的核磁共振谱和X射线单晶分析,确证了这类化合物的分子结构。

Eleven substituted 2-(2'-phenylpropenyl)benzoxazoles and nine substituted 2-(2'-pnenyl-propenyl)-5-methylbenzoxazoles were synthesized by the modified Wittig reaction. All of them were identified by elemental analysis, IR and NMR spectrometry. The crystal and molecular structure of 2-(2'-bromophenyl-propenyl)benzoxazole were determined by X-ray diffraction method.
