The palladium-catalysed coupling of p-bromo azo dyes 4 with styrenes 6 and arylacetylenes 9 provides arylazostilbenes 7 and -tolanes 10, respectively, in fair-to-good yields. Likewise, coupling of azoxy compound 5 with styrenes 6 forms the arylazoxystilbenes 8 in high yields. The influence of substituentes on light absorption of the new dyes as well as on the the C-13-NMR shifts of the azotolanes 10 are discussed.
