Synthesis of ferrocenyl thioketones and their reactions with diphenyldiazomethane
Mlostoń, Grzegorz,Hamera, Róza,Heimgartner, Heinz
, p. 2125 - 2133 (2015/12/23)
A series of ferrocenyl ketones were obtained via the Friedel-Crafts acylation with mixed anhydrides using ferrocene as a nucleophilic agent or ferrocene carboxylic acid as a precursor of the electrophilic species. The ketones obtained thereby undergo smooth thionation (tetrahydrofuran, 65°C) with Lawesson's reagent. The ferrocenyl thioketones react with diphenyldiazomethane via N2 elimination to afford the hitherto unknown ferrocenyl-substituted thiiranes.
Catalysis by Palladium Salts. Part 2. Palladium-catalysed Carboxylation with Carbon Monoxide of Aromatic Compounds Working under Mild Conditions
Ugo, Renato,Chiesa, Anna
, p. 2625 - 2630 (2007/10/02)
The carboxylation with CO of aromatic C-H bonds, catalysed by palladium acetate, occurs with good yields and under mild conditions (1 atm of CO and 20-50 deg C), with trifluoroacetic acid as solvent and sodium acetate as co-catalyst.The reaction, which is
