The utility of perovskite-based materials in organic synthesis is explored through examination of a series of copper- and palladium-containing perovskites in Ullmann and Sonogashira type reactions. La0.9Ce 0.1Co0.6Cu0.4O3 is identified as an effective catalyst for the synthesis of a range of biaryl ether and thioether functionalities, whilst a Cu- and Pd-containing perovskite is effective in the Sonogashira reaction. These results suggest that perovskites may be useful leads in the search for new catalysts and reagents for organic synthesis.
Palladium nanoparticles embedded in improved mesoporous silica: A pH-triggered phase transfer catalyst for Sonogashira reaction

An efficient and reusable pH-responsive mesoporous silica nanocomposite shuttle-supported palladium catalyst was synthesized, which efficiently promotes the Sonogashira reaction in water-based biphasic systems. This catalyst of shell-embedded palladium nanoparticles is highly dispersed in organic phase in a pH range from 9 to 10 just like a homogeneous catalyst, and can be separated and reused like a heterogeneous one by adjusting the pH value of the aqueous medium. In addition, Sonogashira reactions can be performed without a copper co-catalyst.
The electronic structure and second-order nonlinear optical properties of donor-acceptor acetylenes: A detailed investigation of structure-property relationships
Stiegman,Graham, Eva,Perry, Kelly J.,Khundkar, Lutfur R.,Cheng,Perry, Joseph W.
, p. 7658 - 7666 (2007/10/02)
A series of donor-acceptor acetylene compounds was synthesized in which systematic in both the conjugation length and the donor-acceptor strength were made. The effect of these structural changes on the spectrcscopic electronic proprties of the molecules
