Synthesis of multinuclear Rh(I) complexes bearing triazolylidenes and their application in C-C and c-Si bond forming reactions

Multidentate carbene ligands are valuable frameworks for the preparation of carbene complexes displaying higher nuclearity. In the present work, we report the synthesis of a series of mono- to tetra-[Rh(COD)I] complexes (3a- d) supported by mesoionic triazol-5-ylidenes. The general synthetic procedure involves the one step reaction of the appropriate triazolium (2a-d) salt in the presence of KHMDS and stoiquiometric amounts of the rhodium(I) precursor. Treatment of complexes 3a-d with an excess of carbon monoxide allows for the quantitative preparation of complexes 4a-d featuring a [Rh(CO)2I] fragment used for the detemination of the donor properties of the new triazolylidene ligands. All complexes have been fully characterized by means of 1H and 13C NMR spectroscopy, melting point, elemental analysis, and in the case of complex 3a, by X-ray crystallography. Comparison of the catalytic activity of the new rhodium complexes in C-C and C-Si bond forming processes demonstrate the enhanced performance of the tetranuclear species suggesting the possibility of strong cooperative effects in these multinuclear complexes.

Preparation of Optically Active cis-Cyclopropane Carboxylates: Cyclopropanation of α-Silyl Stryenes with Aryldiazoacetates and Desilylation of the Resulting Silyl Cyclopropanes

Optically active cis-cyclopropane carboxylates are prepared via the Rh2(S-PTAD)4-catalyzed cyclopropanation of α-silyl styrenes with aryl diazoacetates followed by desilylation of the resulting silyl cyclopropane carboxylates. The co

Stereospecific Arylation of Alkenylsilanes with Arylpalladium Acetates

Alkenyltrimethylsilanes ((E)- and (Z)-RCH=CHSiMe3: R = H, Ph, n-C6H13 and CH3OCH2) stereospecifically reacted at 40 deg C or room temperature with in situ generated phenylpalladium acetate to produce R(Ph)C=CSiMe3 and RCH=C(Ph)SiMe3 with inversion of their geometry.The arylation of CH2=CHSiMe3 with arylpalladium acetates gave (E)-ArCH=CHSiMe3 (Ar = XPH; X = H, 4-Me, 4-MeO, 4-Br, 4-I, 4-EtOCO, and 4-NO2) in good yields.
