- Nickel-Catalyzed Reductive Cross-Coupling of Aryl Bromides with Vinyl Acetate in Dimethyl Isosorbide as a Sustainable Solvent
-
A nickel-catalyzed reductive cross-coupling has been achieved using (hetero)aryl bromides and vinyl acetate as the coupling partners. This mild, applicable method provides a reliable access to a variety of vinyl arenes, heteroarenes, and benzoheterocycles, which should expand the chemical space of precursors to fine chemicals and polymers. Importantly, a sustainable solvent, dimethyl isosorbide, is used, making this protocol more attractive from the point of view of green chemistry.

Planar tridentate Lewis acids were synthesised by hydrosilylation reactions of triethynylbenzene with chlorosilanes. Hydrogenation of the rigid triethynylbenzene using hydrogen in the presence of Lindlar's catalyst resulted in the formation of trivinylben

- Removal, recovery, and recycling of triarylphosphonium-supported tin reagents for various organic transformations
-
Phosphonium-supported tin reagents and catalysts were prepared and were shown to be effective in Stille couplings, radical dehalogenations, radical cyclizations, and carbonyl allylations. Not only could the tin residues be removed from the crude reaction mixture through a phase separation process but also they could be recovered and recycled.

- New heck-type coupling reactions of natural tetrapyrroles - Synthesis of porphyrinoligomers bridged by divinyl- and trivinylbenzene
-
Using palladium(0)-catalyzed coupling reactions we were able to synthesize mono-, di-, and trimeric porphyrins linked by di- and trivinylbenzenes. The reactions were carried out with palladium(II) acetate in DMF under phase-transfer conditions. These coupling conditions are new in the field of porphyrin chemistry and proved to be a useful tool in the synthesis of C-C linked oligomeric porphyrins, as these compounds can be obtained in a simple one pot reaction with good yields.

- Flash Pyrolysis of Selenides. Syntheses of Bibenzyls, Olefins, and Related Compounds
-
Pyrolyses of a series of selenides and diselenides were studied. Selenides and diselenides bound with an active methylene group like benzyl gave a variety of substituted bibenzyls and related ethane derivatives in high yields. Other diselenides were easily caused to cleave to give various aromatic and aliphatic olefins in good yields together with elemental selenium. Lepidopterene, paracyclophane, and benzocyclobutene were prepared by thermal cleavage of their corresponding phenylselenomethyl-substituted compounds as an application of the pyrolysis concerned.
