A programmed synthesis of privileged arylthiazoles via sequential C–Hcouplings catalyzed by palladium or nickel catalysts has been accomplished. This versatile protocol can supply all possible arylthiazole substitution patterns (2-aryl, 4-aryl, 5-aryl, 2,4-diaryl, 2,5-diaryl, 4,5-diaryl, and 2,4,5-triaryl) from an unfunctionalized thiazole platform by 11 distinct synthetic routes. We have generated

A convergent synthesis of various triphenylamine derivatives led to a small library of fluorophores showing different photophysical properties. The position of the pyridinium (ortho, meta, para) has an influence on the color of the fluorophore (from yellow to red) as well as on its cellular localization (mitochondria or nucleus).
