The synthesis of a family of differently substituted 5- and 4,4′-ethynyl-bpy PtII bisacetylide complexes (bpy = 2,2′-bipyridine) and their postfunctionalization using clickchemistry is described. CuI-catalyzed azide–alkyne [3+2] cycloaddition was an efficient method to decorate the PtII complexes with a manifold of moieties in high yields. The absorption and emission properties and the electrochemical

to the synthesis of 2-hydroxyaryl-alkenylphosphine oxides and dialkyl (diaryl)-(2-methyl-4-oxopent-2-yl)phosphine oxides was developed that involves an interaction of Grignard reagents with available benzo[e]-1,2-oxaphosphorinines and 1,2-oxaphospholene-2-oxide. This approach allows obtaining target compounds with a high yield. The synthesized phosphine oxides proved to be highly efficient extractants
The compounds are 4-aryl substituted buta-2,3-dienoic acids and esters thereof which may also be lower alkyl-substituted at any of the 2- and 4- positions, e.g., 4-(p-methoxyphenyl)-2-methyl-buta-2,3-dienoic acid. The compounds are useful as pharmaceuticals, e.g., as antiinflammatory agents and hypolipidemic agents.
