Synthesis and Emission Properties of 1,6-Methano[10]annulene-3,4-dicarboximides
摘要:
A mixture of 1,6-methano[10]annulene-3,4-dicarboximide (le) and 1,6-methano[10]annulene-3,4-dicarboxylic anhydride (3) was obtained through a two-step sequence involving cyanation and subsequent hydrolysis from ethyl 4-bromo-1,6-methano [10]annulene-3-carboxylate (5). Alkylations of le provided If and 1g, and the nucleophilic substitution of p-fluoronitrobenzene with le yielded 1i. Copper-catalyzed arylations of le with arylhalides gave la and 1h. Reactions of 3 with anilines afforded la and 1h. Emission properties of the imides obtained are also reported.

were aerobically oxidized to their oxygenated products via a novel catalytic system using N ‐hydroxy‐1,6‐methano[10]annulene‐3,4‐dicarboximide (2 ) and cobalt(II) acetate under mild conditions. A radical mechanism has been proposed to account for the aerobic oxidation of these hydrocarbons. The 2 /Co(OAc)2 catalytic system was optimized and the reaction scope was explored.
