is a Group IIIA metal, X is a halogen and n is an integer fro 1 to 3. Such monoalkyl Group VA metal dihalide compounds are substantially free of oxygenated impurities, ethereal solvents and metallic impurities. Monoalkyl Group VA metal dihydride compounds can be easily produced in high yield and high purity by reducing such monoalkyl Group VA metal dihalide compounds.
揭示了通过将VA族金属三卤化物与有机锂试剂或化合物RnM1X3−n(其中R是烷基,M1是III A族金属,X是卤素,n是1到3的整数)反应,以高产率和高纯度制备单烷基VA族金属二卤化合物的方法。这种单烷基VA族金属二卤化合物基本上不含氧杂质、醚溶剂和金属杂质。通过还原这种单烷基VA族金属二卤化合物,可以轻松地高产率和高纯度地生产单烷基VA族金属二氢化合物。
