Disclosed are methods of preparing monoalkyl Group VA metal dihalide compounds
in high yield and high purity by the reaction of a Group VA metal trihalide with
an organo lithium reagent or a compound of the formula RnM1X3-n,
where R is an alkyl, M1 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.
