产品介绍

4-乙炔基苯甲醚可直接从DMF-二甲基乙缩醛以高收率形成相应的炔丙基醛，无需制备乙炔盐。受体环丙基甲基硅烷的1,3-偶极环加成能够以高收率形式生成功能化环戊烯。 4-乙炔基苯甲醚可用作有机合成的合成砌块，也可用于Sonogashira偶联反应。应用使用 4-乙炔基茴香醚：通过 [4 + 2] 环加成合成光致发光 1,2-二氢膦以及芳基硼酸和叠氮化钠在铜催化的三取代 1，2，4-三唑的三组分合成中的作用在一项研究中，金 (III) 催化炔烃的氢化胺化反应生成了 N-乙烯吲哚。受体-环丙基甲基硅烷通过1，3-偶极环加成可以良好的产率生成官能化的环戊烯。可直接从DMF-二甲基乙缩醛以高收率形成相应的炔丙基醛，无需制备乙炔盐。 4-Ethynylanisole forms the corresponding propargyl aldehyde in good yield directly from DMF-dimethyl acetal without the need for making an acetylide salt. 1,3-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields. 4-Ethynylanisole can be used as a building block in organic synthesis and also used in sonogashira coupling reactions. Application 1,3-dipolar cycloaddition of acceptor-cyclopropylmethylsilanes affords functionalized cyclopentenes in good yields. 4-Ethynylanisole was used: in the synthesis of photoluminescent 1,2-dihydrophosphinines via a [4 + 2] cycloaddition along with an arylboronic acid and sodium azide in a copper-catalyzed, three-component synthesis of trisubstituted 1,2,4-triazoles in a study of a gold (III)-catalyzed hydroamination of alkynes leading to N-vinylindoles. Forms the corresponding propargyl aldehyde in good yield directly from DMF-dimethyl acetal without the need for making an acetylide salt.
