scheme or table, p. 3504 - 3510 (2010/02/28)
The regioselective copper-catalyzed addition of sp3 C-H bonds adjacent to an oxygen atom to various alkynes has been accomplished under mild reactions conditions in the presence of tertbutyl hydroperoxide to give the corresponding alkenylated p
A novel approach of cycloaddition of difluorocarbene to α-β-unsaturated aldehydes and ketones: Synthesis of gem-difluorocyclopropyl ketones and 2-fluorofurans

A series of gem-difluorocyclopropyl acetals and ketals are easily obtained in moderate yields from the [1 + 2] cycloaddition of difluorocarbene to 1,3-dioxolanes of α,β-unsaturated aromatic aldehydes and ketones. Hydrolysis of these fluorinated compounds under acidic conditions either gives the corresponding gem-difluorocyclopropyl ketones or 1-aryl-2-fluorofuran derivatives through intramolecular carbonium rearrangement with simultaneous ring cleavage.
Phase transfer Wittig reaction with 1,3-dioxolan-2-yl-methyltriphenyl phosphonium salts: An efficient method for vinylogation of aromatic aldehydes

Aldehydes were efficiently transformed into allylic dioxolanes by a Wittig-type reaction, using 1,3-dioxolan-2-yl-methyltriphenylphosphonium bromide under phase transfer conditions. The substituent kinetic effects were studied, and related to Hammett values and electrochemical potentials.
