Abstract
Oxadisilole-fused-3,4-dihydro-2H-naphtho[2,1-e]-1,3-oxazines and 3,4-dihydro-2H-anthra[2,1-e]-1,3-oxazines were synthesized through an eco-friendly Mannich type condensation–cyclization reaction of oxadisilole-fused-1-naphthalenol or 1-anthracenol with formaldehyde and primary amines at ambient temperature in high to excellent yields. The photophysical, electrochemical, and thermal properties of these 3,4-dihydro-2H-anthra[2,1-e]-1,3-oxazine derivatives were also studied.
