Incorporation of π-conjugated spacers at the 2 or 5 position of a 2,5-disubstitutedaryloxazole led to new series of fluorescent dyes. They show emissions from visible to 700 nm along with significant Stokes shift up to 208 nm and a strong solvatochromic fluorescence. These compounds are easily accessible in one step through direct C-H bond functionalization.

[Chemical equation presented] Copper-bottomed catalysis! The direct alkynylation of azoles through a copper-based C - H bond activation, using alkynylbromides as the coupling partner, has been developed (see scheme). The method is very rapid, is functional-group tolerant, and provides a straightforward entry to diverse alkynyl heterocycles that is complementry to the Sonogashira reaction.
