Cp_2TiCl_2/i-BuMgBr体系形成的钛氢化试剂与炔硒醚反应生成端炔与深蓝色钛硒化物,后者在空气中被氧化为二醚,与酰氯反应,高产率地形成对应的硒代酯.
The titanium hydrogenation reagent formed by the Cp_2TiCl_2 / i-BuMgBr system reacts with the alkynyl selenide to form an alkyne and a dark blue titanium selenide, which is oxidized to diether in the air and reacts with the acid chloride to form the corresponding selenoester .
