Ferrocenephosphonates: Copper-Promoted Synthesis and Further Functionalization

نویسندگان

چکیده

Abstract Ferrocenephosphonates make up an important class of organometallic derivatives with a wide range useful applications in organic synthesis and coordination chemistry. Here, approach to ferrocenephosphonates based on copper-promoted Hirao coupling is reported. Further functionalizations regioselective deprotolithiation both Negishi Suzuki–Miyaura cross-coupling reactions are also described reach original derivatives.

Phosphazene base-promoted functionalization of aryltrimethylsilanes.

The activation of Ar-Si bonds in aryltrimethylsilane was investigated using a catalytic amount of t-Bu-P4 base and selective functionalizations of aryltrimethylsilanes in the absence of strong electron withdrawing groups on the aromatic rings were accomplished.

Nickel promoted functionalization of CO2 to anhydrides and ketoacids.

The reductive functionalization of carbon dioxide into high value organics was accomplished via the coupling with carbon monoxide and ethylene/propylene at a zerovalent nickel species bearing the 2-((di-t-butylphosphino)methyl)pyridine ligand (PN). An initial oxidative coupling between carbon dioxide, olefin, and (PN)Ni(1,5-cyclooctadiene) afforded five-membered nickelacycle lactone species, wh...

Synthesis of tetrasubstituted unsymmetrical 1,4-enediones via copper-promoted autotandem catalysis and air as the oxidant.

An efficient procedure has been developed for the preparation of tetrasubstituted unsymmetrical 1,4-enediones via copper-promoted autotandem catalysis and air as the oxidant. Various N-nucleophiles are compatible with this reaction, such as morpholine, piperidine, pyrrolidine, arylamines, pyrazole, imidazole, benzimidazole, and benzotriazole. This reaction also has significant advantages in eas...

Acetic Acid Promoted Redox Annulations with Dual C–H Functionalization

Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with 2-alkylquinoline-3-carbaldehydes as well as the corresponding 4-alkyl isomers and pyridine analogues. These processes involve dual C-H bond functionalization. Acetic acid is used as a cosolvent and acts as the sole promoter of these transformations.
