Suzuki-Miyaura cross-coupling and Heck-Mizoroki reactions catalysed by palladium on carbon nanofibres
Yamamoto, Kyoko,Thiemann, Thies
, p. 246 - 250 (2011)
Platelet, tubular and herringbone carbon nanofibres were doped with Pd under various conditions. The catalysts were analysed for their Pd-content and as to the size distribution of the Pd particles. The Pd-doped carbon nanofibres were screened for their c

Carbenes are one of the most appealing, well-explored, and exciting ligands in modern chemistry due to their tunable stereoelectronic properties and a wide area of applications. A palladium complex (BICAAC)2PdCl2 with a recently discovered cyclic (alkyl)(amino)carbene having bicyclo[2.2.2] octane skeleton (BICAAC) was synthesized and characterized. The enhanced σ-donating and π-accepting ability of this carbene lend a hand to form a robust Pd-carbene bond, which allowed us to probe its reactivity as a precatalyst in Heck-Mizoroki and Suzuki-Miyaura cross-coupling reactions with low catalyst loading in open-air conditions. The diverse range of substrates was explored for both the cross-coupling reactions. To get a better understanding of the catalytic reactions, several analytical techniques such as field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and powder X-ray diffraction were employed in a conclusive manner.
Monodentate phosphorus-coordinated palladium(II) complexes as new catalyst for Mizoroki-Heck reaction of aryl halides with electron-deficient olefins

Four novel palladium(II) complexes coordinated by phosphorus atoms from both 3,5-disubstituted-1H-1,2,4-diazaphospholes in monodentate fashion were developed as efficient catalyst for the Mizoroki-Heck reaction of aryl halides with electron-deficient olefins. The coupling reaction of aryl halide bearig different functional groups with olefin derivatives took place and the corresponding products were isolated in good to excellent yields under optimal conditions. The procedure exhibits good functional group tolerance and wide substrate scope. This Mizoroki-Heck reaction was further achieved using Pd(OAc)2 and 3,5-di-isopropyl-1H-1,2,4-diazaphospholes as combined catalyst, which provide the convenient and alternative method in organic synthesis
Ligand-free PdCl2-catalyzed heck reaction of arylboronic acids and olefins under reusable TBAB/H2O conditions

A novel method was developed for Heck reaction of olefins and arylboronic acids using a ligand-free PdCl2 catalyst to afford the coupling products with excellent regio- and stereoselectivity. It is noteworthy that the PdCl2/CuSO4/K2CO3/TBAB/H 2O system can be recovered and used for three cycles directly. Georg Thieme Verlag Stuttgart, New York.
