Abstract: A process for reducing the level of tri-substituted phosphine, arsine and/or stibine oxide from a mixture comprising a desired product and at least one such oxide is provided, comprising the addition of a metal salt to the mixture to form a complex with the oxide, and removing the complex from the mixture. This process has particular utility for removing triphenylphosphine oxide from a mixture--a task that was previously hard to perform.
