(10% Pd/C) efficiently catalyzes the (retro-)Michael addition of activatedmethylenecompounds 2a-d, such as malononitrile (2b), to mono- and doubly activated styrenes 1a-h to give the adducts 3a-1. The scope and limitations are described. The Knoevenagel condensation reaction of benzaldehyde and 2b or ethyl cyanoacetate (2c) is also catalyzed by 10 % Pd/C. In these cases the Michaeladducts can even

Palladium-catalyzed regiodivergent allylic C−H functionalizations were established via remote substitution, which provides a novel model for the seldomly studied migratory Tsuji–Trost reaction. 1,4-Hydrofunctionalization of a conjugated diene intermediate was demonstrated to be feasible via a newly synthesized bisphosphine ligand.

Canyou kill two catalysts with one chloride? Thiourea/urea catalysts are sensitive to inhibition by chloride salts, but here we find that they appear to be too sensitive. Are two catalysts inhibited by a single chloride ion, or are there two catalysts involved in the reaction? Our kinetic detective story suggests the latter!
