- Copper(I)-promoted palladium-catalyzed cross-coupling of unsaturated tri-n-butylstannane with heteroaromatic thioether
-
(Matrix presented) Palladium-catalyzed cross-coupling of vinyl- and arylstannanes with π-electron-deficient heteroaromatics was performed in good yields. This Stille-type reaction was carried out with a methylthioether function as an electrophile in the presence of a copper(I) bromide-dimethyl sulfide complex.

- Palladium-catalyzed 3-thiomethyltriazine-boronic acid cross coupling: Easy access to 3-substituted-1,2,4-triazines
-
The palladium-catalyzed coupling reaction of 3-thiomethyl-1, 2,4-triazine 1 with different organoboron compounds in the presence of copper(I) 3-methylsalicylate proceeds to afford the corresponding 3-substituted-1,2,4-triazines in good yield. This approach leads very easily to a large range of C-5 and C-6 unsubstituted as-triazines.

The induction, resonance, and Hammett constants of 3-, 5-, and 6-asym-triazinyl groups were calculated from the data of 1H, 13C, 19F NMR spectra of isomeric aminophenyl-, hydroxyphenyl-, phenyl-, and fluorophenyl-asym-triazines.
