P4 + CO

The reaction between phosphorus (P4) and carbon monoxide (CO) can lead to the formation of phosphorus-containing compounds, depending on the conditions such as temperature and pressure.

One of the potential products of this reaction is diphosphorus monoxide (P2O), although this formation is more commonly considered in theoretical contexts or under specific conditions.

In a general sense, phosphorus can react with carbon monoxide at elevated temperatures to produce various phosphorus oxides and phosphides, but the reaction specifics could vary. For practical laboratory syntheses or industrial applications, the pathways and products must be carefully controlled.
