Trioctylphosphine is an organophosphorus compound with the formula P(C₈H₁₇)₃ sometimes abbreviated TOP.^[1] It is usually encountered as a syrup. The compound is colorless.

Reactions

Trioctylphosphine 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]
