Regio- And Stereoselective Synthesis of Thiazole-Containing Triarylethylenes by Hydroarylation of Alkynes

Thiazole-containing π-conjugated moieties are important structural units in the development of new electronic and photochromic materials. We have developed a Pd-catalyzed syn-hydroarylation reaction of diaryl alkynes with thiazoles that provides access to thiazole-containing triarylethylenes. Pd(II) complexes derived from Pd(0) species and carboxylic acids facilitated C-H functionalization of the unsubstituted thiazole with high C5 selectivity. The catalytic system was also compatible with other azoles, such as oxazoles and a pyrazole, allowing the stereoselective syntheses of various trisubstituted olefins.

Multifunctional Photoadditions of Stilbene to Derivatives of Caffeine and Benzothiazole

Electronically excited stilbene (1*) is trapped by 8-substituted caffeine derivatives (2a-f) or 2-chloro- (14) and 2-aminobenzothiazole (21) with variable results.While the electron-rich systems (2c,d) produce mostly propellanes, the halogeno compounds 2a,b and 14 react predominantly via insertion into the C-halogen bond.With 14 there occurs also some C-S insertion, with 21 only N-H insertion.Numerous succeeding reactions are elucidated and the reaction mechanisms discussed.Stilbene (1) photoadds hydrogen chloride to yield 16.
