Catalytic Chemoselective and Stereoselective Semihydrogenation of Alkynes to E-Alkenes Using the Combination of Pd Catalyst and ZnI2

An efficient E-selective semihydrogenation of internal alkynes was developed under low dihydrogen pressure and low reaction temperature from commercially available reagents: Cl2Pd(PPh3)2, Zn0, and ZnI2. Kinetic studies and control experiments underline the significant role of ZnI2 in this process under H2 atmosphere, establishing that the transformation involves syn-hydrogenation followed by isomerization. This simple and easy-to-handle system provides a route to E-alkenes under mild conditions.

Palladium-catalyzed hydrophenylation of alkynes with sodium tetraphenylborate under mild conditions

(Chemical Equation Presented) In an aqueous solution of acetic acid, PdCl2(PPh3)2 showed high catalytic activity for the hydrophenylation of both terminal and internal alkynes with sodium tetraphenylborate (NaBPh4) under mild conditions, affording phenyl alkenes in moderate to excellent yields.

Solventless Suzuki coupling reactions on palladium-doped potassium fluoride alumina

A solventless Suzuki coupling reaction has been developed which utilizes a commercially available potassium fluoride alumina mixture and palladium powder. The new reaction is convenient, environmentally friendly, and generates good yields of the coupled products. Aryl iodides react faster than the bromides or chlorides; aryl groups are also more reactive than alkenyl groups, which react faster than alkyl groups. The use of microwave irradiation accelerates the reaction, decreasing reaction times from hours to minutes. The palladium powder catalyst can be recycled using a simple filtration and washing sequence without loss of catalytic activity.
