Tris (pyrazolyl) borates, first reported about 40 years ago, are a very useful class of
monoanionic, nitrogen-based, auxiliary ligands in coordination and organometallic and …

Two families of catalysts containing trispyrazolylborate (Tpx) or N-heterocyclic carbenes
(NHC) with the group 11 metals have proven useful for several reactions involving the …

A simple copper-based catalytic system has been developed for the carbon− hydrogen
amidation reaction. The copper− homoscorpionate complex TpBr3Cu (NCMe) catalyzes the …

The olefin aziridination reactions catalyzed by copper and silver complexes bearing
hydrotris (pyrazolyl) borate (Tpx) ligands have been investigated from a mechanistic point of …

The Cu (I) β-diketiminate [Me2NN] Cu (η2-ethylene)(2) catalyzes the cyclopropanation of
styrene with N2CPh2 to give 1, 1, 2-triphenylcyclopropane in 67% yield. Addition of N2CPh2 …

Controlling the selectivity of reactive intermediates is a major goal of organic chemists.
Carbenes generated by thermal or photochemical extrusion of nitrogen from diazo …

The complex TpBr3Cu (NCMe) catalyzes, at room temperature, the insertion of a nitrene
group from PhINTs into the carbon− hydrogen bond of cyclohexane and benzene, as well as …

Polyfluorinated, electron-withdrawing, and sterically demanding supporting ligands are of
significant value in chemistry. Here we report the assembly and use of a bis (pyrazolyl) …

The complex IPrCuCl (1) catalyzes the transfer of the: CHCO2Et group from ethyl
diazoacetate (EDA) to unsaturated and saturated substrates (olefins, amine, alcohols) with …

The installation of metallo-ligands in metal–organic frameworks (MOFs) is an effective
means to create site-isolated metal centers toward single-site heterogeneous catalysis …
