氢化镁与吡啶的反应:形成H 3 Mg 2 NC 5 H 6,HMgNC 5 H 6和Mg(NC 5 H 6)2
摘要:
氢化镁与过量吡啶在室温下的反应导致形成可溶性双(N-二氢吡啶基)镁,其通过NMR光谱显示,其包含结合至镁的1,2-和1,4-二氢吡啶基。已显示在60℃下进行的类似反应形成仅包含1,4-二氢吡啶基的双(N-二氢吡啶基)镁。在吡啶与氢化镁的受控反应中还报道了H 3 Mg 2(NC 5 H 6)和HMg(NC 5 H 6)的形成。

Solubility problems solved: The first examples of discrete soluble zincdihydride adducts with NHC ligands reacted with CO2 to produce formate species and efficiently catalyzed the dehydrocoupling of silanes with methanol. These compounds were characterized both in solution and in the solid state (see picture).

Zinc dihydride reacts with a gallium(I) reagent by reversible oxidativeaddition to provide di- and trimetallic hydridogallyl zinc complexes. The position of oxidative addition-reductive elimination equilibria can be controlled by coordination/decoordination of TMEDA.

Matrix-isolation experiments give evidence that broad-band UV-vis irradiation (200 less than or equal to lambda less than or equal to 800 nm) of an Ar matrix doped with SiH4 and a group 12 metal atom M (M = Zn, Cd, or Hg) induces metal insertion into an Si-H bond to give the silyl metal hydride molecule HMSiH3 as the primary product. Si2H6 is a second product, irrespective of the identity of M, while the binary hydride MH2 is also formed when M = Zn or Cd. The products have been identified by their IR spectra and experiments with SiD4, together with the results of quantum chemical calculations, have provided the means of authentication. The properties of the HMSiH3 molecules are compared with those of related species, and consideration is given to how the products come to be formed.
