Calcium vapor (atom) when cocondensed with various solvents at 77 K was found to be very reactive toward alkyl and aryl halides. A series of organocalcium halides was prepared in good yields by addition of alkyl or aryl halides to the resultant calcium atom-solvent slurries at ambient temperatures.
发现
钙蒸气(原子)在77 K时与各种溶剂共缩合时,对烷基和芳基卤化物的反应性非常强。通过在环境温度下将烷基或芳基卤化物添加到所得的
钙原子-溶剂浆液中,以高收率制备了一系列有机卤化
钙。
