文摘

5,5鈥?Disubstituted-3,3鈥?bisisoxazoles are prepared in one step by the dropwise addition of aqueous potassium hydrogen carbonate to a mixture of dichloroglyoxime and terminal alkynes. The reaction exhibits a striking preference for the 5,5鈥?disubstituted 3,3鈥?bisisoxazole over the 4,5鈥?regioisomer. Organometallic iridium and rhenium bisisoxazole complexes are luminescent with emission wavelengths varying depending upon the identity of the 5,5鈥?substituent (phenyl, butyl).
