Chromenone-diazonium-BF4 salts were isolated as stable powders by diazotization of the 7-amino-derivatives with NaNO2/HBF4. The 7-Fluoro-derivatives were synthesized by fluorodediazoniation in [BMIM][PF6], while

An efficient tandem synthesis of chromones from: O -bromoaryl ynones and benzaldehyde oxime

An effective transition-metal-free strategy was developed for the preparation of chromones from o-bromoaryl ynones and benzaldehyde oxime through sequential C-O bond formation. This cyclization reaction could well tolerate a wide range of functional groups, and the corresponding chromones were given in moderate to excellent yields. Mechanistically, benzaldehyde oxime as a hydroxide source and 1,3-diketone derivatives as reaction intermediates were involved in this transformation.
