Palladium-catalyzed cross-coupling of organolead(IV) triacetates with terminal alkynes

The palladium-catalyzed carbon-carbon bond formation of organolead(IV) triacetates with terminal alkynes was accomplished with Pd2(dba)3·CHCl3 (5mol%) and CuI (10mol%) in the presence of NaOMe (2 equiv.) in MeOH/CH3/

Photochemistry of 1-Aryl-4-(pentamethyldisilanyl)-1,3-butadiynes

All the 1-aryl-4-(pentamethyldisilanyl)-1,3-butadiynes (1a-d) synthesized show strong phosphorescence emissions with triplet energies around 218-260 kJ/mol.Laser photolysis of 1-(p-nitrophenyl)-4-(pentamethyldisilanyl)-1,3-butadiyne (1d) in polar solvents results in the formation of an interesting transient (zwitterion species) through intramolecular electron transfer from disilanyl to the nitro group in the triplet excited state.Irradiation of 1d in methanol or ethanol gives 1-(p-nitrophenyl)-1,3-butadiyne (8) through C-Si bond cleavage from the transient.Photolysis of 1-phenyl-4-(pentamethyldisilanyl)-1,3-butadiyne (1a), 1-(1-naphthyl)-4-(pentamethyldisilanyl)-1,3-butadiyne (1b), and 1-(p-methoxyphenyl)-4-(pentamethyldisilanyl)-1,3-butadiyne (1c) in methanol yields photoaddition products (2-7) through silacyclopropene intermediates.
