A Singlet Biradicaloid Zinc Compound and Its Nonradical Counterpart.
Metal ions with radical centers in their coordination sphere are key participants in biological and catalytic processes. In the present study, we describe the synthesis of the cAAC:ZnCl adduct (1) using a cyclic alkylaminocarbene (cAAC) as donor ligand. Compound 1 was treated with 2 equiv of KC and...

In the present study, we describe the synthesis of the cAAC:ZnCl adduct (1) using a cyclic alkylaminocarbene (cAAC) as donor ligand. Compound 1 was treated with 2 equiv of KC and LiB(sec-Bu)H to yield a deep blue-colored dicarbene zinc compound (cAAC)Zn (2) and the colorless hydrogenated zinc compound (cAACH)Zn (3), respectively. Compounds 2 and 3 were well characterized by spectroscopic methods and single-crystal X-ray structural analysis. Density functional theory calculations were performed for 2 which indicate that this molecule possesses a singlet biradicaloid character. Moreover, we show the application of 2 in CO activation, which yields a zwitterionic cAAC·CO adduct. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2013 holdings: @attributes: islocal: N |
