Abstract:
An asymmetric t BuPOCNTriaz type pincer ligand containing a triazole arm was developed and used to generate iridium pincer complexes with different oxygen atom binding ancillary ligands. The structure and reactivity of the complexes [(t BuPOCNTriaz)Ir(H)(O2CCH3)], [(t BuPOCNTriaz)Ir(H)(acac)], and [(t BuPOC)Ir(H)(O2CCF3)] and its cationic derivatives were studied. The complexes could be successfully employed in the catalytic transfer dehydrogenation of alkanes as well as of unsaturated heterocycles.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation reactions,...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.

Heterogeneous Catalysis
Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the...
