The palladium-catalyzed carbon-carbon bond formation of organolead(IV) triacetates with terminalalkynes was accomplished with Pd2(dba)3·CHCl3 (5 mol%) and CuI (10 mol%) in the presence of NaOMe (2 equiv.) in MeOH/CH3CN (1:1) at room temperature.

Organolead acetates can be carbonylated in the presence of Pd2(dba)3·CHCl3 (5 mol%) and NaOMe (5 equiv.) in CH3CN under atmospheric pressure of carbon monoxide at room temperature to afford symmetrical ketones.

decarboxylative asymmetricallylicalkylation (DAAA) was optimized with 2,4,6-trimethoxyphenyl as the aryl-containing substrate. A screen of chiral P,N- and P,P-based ligands showed that the ANDEN-phenyl Trost ligand was the most effective, affording the corresponding α-allyl–α-aryl oxindole product in 96% yield and 99% ee. A substrate scope of a further 12 α-aryl–β-amido allyl ester substituted oxindoles showed

Novel stilbene-based triarylamines with dehydroabietic acid methyl ester moieties have been synthesised by palladium catalysed C–N coupling reactions. The presence of the bulky dehydroabietic acid group increases solubility, hinders crystallisation and permits their sublimation while preserving their electronic and optical characteristics. This makes them good candidates for various molecular electronic applications. We report a detailed characterisation of their electrochemical, spectroscopic and photophysical properties. In addition, the thermal stability and behaviour is discussed with reference to the potential for preparation of stable thin films.
