Controllable Isomerization of Alkenes by Dual Visible-Light-Cobalt Catalysis

We report herein that thermodynamic and kinetic isomerization of alkenes can be accomplished by the combination of visible light with Co catalysis. Utilizing Xantphos as the ligand, the most stable isomers are obtained, while isomerizing terminal alkenes over one position can be selectively controlled by using DPEphos as the ligand. The presence of the donor–acceptor dye 4CzIPN accelerates the reaction further. Transformation of exocyclic alkenes into the corresponding endocyclic products could be efficiently realized by using 4CzIPN and Co(acac)2 in the absence of any additional ligands. Spectroscopic and spectroelectrochemical investigations indicate CoI being involved in the generation of a Co hydride, which subsequently adds to alkenes initiating the isomerization.

Tandem reactions involving 1-silyl-3-boryl-2-alkenes. New access to (Z)-1-fluoro-1-alkenes, allyl fluorides, and diversely α-substituted allylboronates

The reactions of 1-silyl-3-boryl-2-alkenes with various electrophilic reagents (Selectfluor, N-halosuccinimides, benzhydryl, and propargylic alcohols in the presence of a Lewis acid, N-alkoxycarbonyliminium ion) have been investigated as new routes to α-substituted allylboronates. Further functional transformations, including allylboration, Suzuki coupling, protodeboronation, and cycloisomerization, have been carried out to illustrate the synthetic potential of these γ-borylallylsilanes.

Rhodium-catalyzed allylic substitution reactions with indium(III) organometallics

A novel rhodium-catalyzed allylic substitution reaction using indium organometallics is reported. Aryl- and heteroarylindium reagents reacted in THF at 80 °C with primary and secondary allyl halides and their derivatives under rhodium(I) catalysis to afford the α-substituted products in good yields and with high regio- and stereoselectivity. The reaction takes place with substoichiometric amounts of the triorganoindium reagents, which demonstrates the efficiency of the indium-rhodium transmetallation process in carbon-carbon bond-forming reactions.

Palladium catalyzed isomerization of alkenes: A pronounced influence of an o-phenol hydroxyl group

A novel palladium catalyzed isomerization of alkenes has been found, where an ortho-phenol hydroxyl group has a pronounced influence on the isomerization.

Polysilane-supported Pd and Pt nanoparticles as efficient catalysts for organic synthesis

Polysilane-supported Pd and Pt catalysts have been prepared for the first time, and used successfully in hydrogenation, Suzuki and Sonogashira reactions, and hydrosilylation respectively: the reactions proceeded in high yields, and the catalysts could be recovered almost quantitatively by simple filtration and reused.

Stereochemistry of the Reaction of an Optically Active ?-Allylpalladium Complex with Nucleophiles

The stereochemistry of the reaction of ?-allylpalladium complexes with nucleophiles has been elucidated using optically active (-)-(1S,2R,3R)-di-μ-chloro-bis(1-methyl-3-phenyl-?-allyl)dipalladium(II); dimethyl sodiomalonate and dimethylamine attack a carbon atom of the ?-allyl ligand from the side opposite to the palladium (inversion), and phenyl and allyl Grignard reagents attack the ?-allyl carbon atom from the same side as the palladium (retention).
