Photodimerization of 3-arylindenones in solution and in the solid state was examined. Irradiation of 3-arylindenones in benzene exclusively gave C2-symmetric anti-HH cyclobutane dimers in good yields. In contrast, photolysis in the solid state

1,3-Diarylpropynones were cleanly converted to the corresponding 3-arylindenones in various superacidic media. This new, simple, one-pot reaction proved to be efficient (yields up to 95%) and very fast (reaction time less than 30min).

An efficient synthesis of chiral 3-arylindanones via iridium-catalyzed asymmetric hydrogenation of 3-arylindenones has been developed. The reaction showed good compatibility with various functional groups, delivering a variety of 3-arylindanones in excellent yields and with good enantioselectivities. The reaction was also carried out on a gram-scale, delivering the product in quantitative yield. In addition, the products can be easily derivatized and transformed into natural products and pharmaceutical agents.

In superacids with H0 = -14 to -20, it has been found that 1,3-diarylpropynones ArC≡CCOAr′ are either protonated on oxygen of carbonyl groups with the formation of stable ions ArC≡CC(O +H)Ar′ or undergo further transformations when t
Protonation and cyclization of 1,3-diarylpropynones in superacids

, p. 1769 - 1778 (2007/10/03)
1,3-Diarylpropynones ArC≡CCOAr′ in superacids with H 0 ranging from -20 to - 14 undergo protonation at the carbonyl oxygen atoms to give stable ArC≡CC(O+H)Ar′ ions or at the acetylenic C2 atom with formation of reactive Ar
