Reactions
editTrioctylphosphine reacts with oxygen to form trioctylphosphine oxide. For this reason it is usually handled with air-free techniques.
TOP reacts with elemental selenium to give trioctylphosphine selenide (TOPSe), which is a reagent for the preparation of cadmium selenide and related semiconductors.[2] [3]
