Abstract

5, 5′-Disubstituted-3, 3′-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′-disubstituted 3, 3′- bisisoxazole over the 4, 5′-regioisomer. Organometallic iridium and rhenium bisisoxazole complexes are luminescent with emission wavelengths varying depending upon the ...
