With the assistance of HPLC‐ESI‐MS/MS, the self‐assembly products of serine and histidine penta‐coordinated phosphorus compound were separated and identified. The expectative product was seryl‐histidine dipeptide, but it was found that there was almost equimolar amount of histidyl‐histidine dipeptide as well as seryl‐histidine dipeptide. The mechanism was speculated that there was ligand exchange between penta‐coordinated phosphoryl serine and histidine in the reaction process. As a result, two types of dipeptide were produced.
