Communication: With the aim to obtain flame-retardant epoxy resins, a new g
lycidyl 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 BF3 . Et2O resulted in a polyether wit
h a pendant bulky phosphorylated group. Likewise, the reaction with phthali
c acid anhydride gave the expected dihydroxy ester. However, the reaction w
ith tertiary or primary amines led to isomerization and no polymer was obta
ined.
