The trans -> cis photoisomerization of 1-styrylnaphthalene (1-StN) and two para-halogen-substituted derivatives (Cl- and Br-1-StN) have been studied in solution by laser flash photolysis and by fluorimetric and photochemical methods.Measurements of the fl

A ligand-controlled iridium-catalyzed semihydrogenation of alkynes to E- and Z-alkenes with ethanol was developed. Effective selectivity control was achieved by ligand regulation. The use of 1,2-bis(diphenylphosphino)ethane (DPPE) and 1,5-cyclooctadiene (COD) was critical for the stereoselective semihydrogenation of alkynes. The general applicability of this procedure was highlighted by the synthesis of more than 40 alkenes, with good stereoselectivities. The value of our approach in practical applications was investigated by studying the effects of pinosylvin and 4,4′-dihydroxystilbene (DHS) on zebrafish as a vertebrate model.

The Wittig reaction was used for the synthesis of diarylethylenes containing condensed naphthalene, anthracene, phenanthrene, and pyrene rings.Unlike 9-anthracenecarbaldehyde, which gives the trans isomers almost exclusively in the Wittig reaction with ar
