We describe methods for synthesis of a triad molecular system based on mesoporphyrin II with electron-donor and electron-acceptor moieties for modeling the primary stage of charge separation in photosynthesis, differing in the order of addition of the donor and the acceptor.Using fluorescent spectroscopy, we have demonstrated quenching-containing coppounds.Investigation of the triad and its zinc complex by kinetic fluorescent spectroscopy allowed us to determine the electron transfer rate constants for the triad and for its zinc complex.

This study describes the first para-selective palladium-catalyzed alkenylation of tertiary amines. This regioselective C-H activation was conducted without any chelation moieties. A series of olefins were reacted under mild reaction conditions at 60 °C, and the corresponding products were obtained in good yields with high selectivity.

An arsine-mediated Wittig reaction for the synthesis of olefins is described. After heating triphenylarsine in the presence of an activated alkyl bromide for 30?min, the resulting arsonium salt condensed with aldehydes in as little as 5?min at room temperature, yielding the olefins in high yields. Aromatic, heteroaromatic, and alkyl aldehydes were all suitable substrates for this process.
