“…Albeit with a lower intensity, the parent cation is also discernible (m/z = 173). As observed previously by both electron impact and photodissociation studies, 38,41,42 metastable decay from the parent ion leads to the fragment [Co(CO) 2 + (m/z = 71) is observed as the only fragment where an internal ligand bond is broken rather than the metal-ligand bonds.…”

“…Thus, above 0.2 eV, intensity changes in the electron beam should not influence the DEA cross section values significantly. Close to 0 eV, however, the electron current can be up to 50% lower than measured at the plateau above 0.2 eV, potentially causing under estimation of the cross section for [Co(CO) 2 …”

“…We have thus not corrected the DEA cross sections to account for mass discrimination, but we also estimate their accuracy to be generally within a factor of two. These might, however, be somewhat larger for the [Co(CO) 2 …”

“…Its metal complexes, particularly the carbonyl derivatives cobalt octacarbonyl and cobalt tricarbonyl nitrosyl, have proven to be useful for both homogeneous 1 and heterogeneous catalyses. 2 The high volatility of Co 2 (CO) 8 and Co(CO) 3 NO make them suitable candidates for chemical vapour deposition (CVD), allowing the deposition of pure 3 or composite cobalt films for microelectronics and information technology. [4][5][6] With the advancement of nanotechnology tools and in particular focused electron beam induced deposition (FEBID) (for recent reviews on the method, see Utke et al 7 and van Dorp and Hagen 8 ), it has become possible to deposit more localized, three-dimensional structures.…”

The following article appeared as: Engmann, S., Stano, M., Papp, P., Brunger, M.J., Matejcik, S. and Ingolfsson, O., 2013. Absolute cross sections for dissociative electron attachment and dissociative ionization of cobalt tricarbonyl nitrosyl in the energy range from 0 eV to 140 eV. We report absolute dissociative electron attachment (DEA) and dissociative ionization (DI) cross sections for electron scattering from the focused electron beam induced deposition (FEBID) precursor Co(CO) 3 NO in the incident electron energy range from 0 to 140 eV. We find that DEA leads mainly to single carbonyl loss with a maximum cross section of 4.1 × 10 −16 cm 2 , while fragmentation through DI results mainly in the formation of the bare metal cation Co + with a maximum cross section close to 4.6 × 10 −16 cm 2 at 70 eV. Though DEA proceeds in a narrow incident electron energy range, this energy range is found to overlap significantly with the expected energy distribution of secondary electrons (SEs) produced in FEBID. The DI process, on the other hand, is operative over a much wider energy range, but the overlap with the expected SE energy distribution, though significant, is found to be mainly in the threshold region of the individual DI processes.

“…[8,9] The Mukaiyama epoxidation is a general protocol that facilitates the epoxidation of an olefin with oxygen by using a sacrificial aldehyde in the presence of various transition metals. [10][11][12] The aldehyde is transformed in situ into a carboxylperoxo radical, facilitating oxygen transfer to the olefin. As a stoichiometric side product, the carboxylic acid is formed.…”

In the present study, CoFe2O4@SiO2@CPTMS nanocomposite was synthesized and the homogeneous chiral Mn‐salen complex was anchored covalently onto the surface of CoFe2O4@SiO2@CPTMS nanocomposite. The heterogeneous Mn‐salen magnetic nanocatalyst (CoFe2O4@SiO2@CPTMS@ chiral Mn (III) Complex) was characterized by different techniques including transmission electron microscopy (TEM), Fourier transform infrared (FT‐IR), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM), powder X‐ray diffraction (XRD) and thermogravimetric analysis (TGA). Then, the aerobic enantioselective oxidation of olefins to the corresponding epoxide was investigated in the presence of magnetic chiral CoFe2O4@SiO2@Mn (III) complex at ambient conditions within 90 min. The results showed the corresponding products were synthesized with excellent yields and selectivity. In addition, the heterogeneous CoFe2O4@SiO2@ CPTMS@ chiral Mn (III) complex has benefits such as high selectivity and comparable catalytic reactivity with its homogeneous analog as well as mild reaction condition, facile recovery, and recycling of the heterogeneous catalyst.
