Triethylborane as an efficient promoter for palladium-catalyzed allylation of active methylene compounds with allyl alcohols

Without prior activation of allyl alcohols, allylation of a variety of active methylene compounds with allyl alcohols proceeds smoothly at rt-50°C in the presence of catalytic amounts of Pd(OAc)2 (1-10mol%), Et 3B (30-240mol%), a phosphine ligand (1-20mol%), and a base (0 to 50-60mol%).

Palladium-catalysed Synthesis of α-Diallylated Ketosulphides of Benzothiazole and their Transformation into Diallyl Thiiranes and Trienes

α-Ketosulphides of benzothiazole 1 react with allylic carbonates in the presence of palladium acetate in dichloromethane under mild conditions affording α,α-diallylated ketosulphides 2 in high yields.Reduction of 2 with sodium borohydride in isopropanol gives episulphides which in turn can be transformed almost quantitatively into trienes.

Palladium-Catalyzed Decarboxylation-Allylation of Allylic Esters of α-Substituted β-Keto Carboxylic, Malonic, Cyanoacetic, and Nitroacetic Acids

Decarboxylation-allylation of allylic β-keto carboxylates using Pd(OAc)2-PPh3 or Pd2(dba)3*CHCl3-dppe as a catalyst proceeds smoothly to give α-allylated ketones.The reaction is highly regioselective.In some cases, diallylated ketones are obtained with allylic esters bearing an active proton(s).Also rhodium, molybdenum, and nickel complexes sre active catalysts in this reaction.Similarly allylic esters of α-substituted malonates, cyanoacetates, and nitroacetate undergo the palladium-catalyzed decarboxylation-allylation to afford allylated acetate, acetonitrile, and nitromethane, respectively.The mechanisms of these palladium-cataly zed decarboxylation-allylations are discussed
