allyl-containing bifunctionalbenzoxazine is synthesized from o-allylphenol, 4,4′-diaminodiphenyl ether, and formaldehyde, followed by isomerization in the presence of chlorotris(triphenylphosphine)rhodium(I)/triethylsilane catalytic system yielding a propenyl-containing benzoxazine, and the chemical structures of the two isomers are confirmed. In the thermal activated polymerization, both isomers undergo the
