With the aim to obtain flame‐retardant epoxy resins, a new glycidyl phosphinate, 9‐(9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide)‐2,3‐epoxypropyl (DOPO‐Gly) was synthesized via a two‐step synthesis. The subsequent reaction of DOPO‐Gly with BF 3 ·Et 2 O resulted in a polyether with a pendant bulky phosphorylated group. Likewise, the reaction with phthalic acid anhydride gave the expected dihydroxy ester. However, the reaction with tertiary or primary amines led to isomerization and no polymer was obtained.
