iron‐catalyzed synthesis of α,β‐unsaturated carboxylic acids from alkynes and carbon dioxide was developed. This reaction proceeds through hydromagnesiation of alkynes followed by carbon dioxide insertion under atmospheric pressure and ambient temperature in the presence of iron and a Grignard reagent as a catalyst and hydride source, respectively. Several symmetrical and unsymmetrical alkynes were transformed
开发了由炔烃和二氧化碳铁催化的α,β-不饱和羧酸的合成方法。该反应通过炔烃的加氢放大进行,然后在大气压和环境温度下分别在铁和格氏试剂作为催化剂和氢化物源的存在下插入二氧化碳。几种对称和不对称炔烃以良好或优异的收率转化为相应的酸。该方法提供了合成乙烯基羧酸的有效途径。
