This invention provides a 2,3-dihydrobenzo[d][1,3]oxaphosphazene derivative of formula (I) and its preparation method. Compound I is constructed by tandem nucleophilic addition (or nucleophilic substitution) and intramolecular S-NAr reaction. This method features simple preparation steps, high yield, and mild reaction conditions, solving the technical problems of complex synthesis steps and harsh conditions in the synthesis of oxaphosphine compounds in traditional prior art.
