实验室中利用CoCl2·6H2O为原料制取三氯化六氨合钴的实验步骤如下: 已知:①Co(NH3)6Cl3在不同温度下水中的溶解度曲线如右图。 ②在Co(NH3)6Cl3溶液中加入一定量盐酸有利于结晶。
A catalyst for alkyne [2+2+2]-cycloaddition reactions, 2-(2,6-diisopropylphenyl)iminomethylpyridine (dipimp)/CoCl2·6H2O/Zn, can be effectively activated by addition of a catalytic amount of dialkyl phthalate to enable reactions that cannot proceed under unactivated conditions. The activation by...
