Here we apply microcrystal electron diffraction (MicroED) to the structural determination of transition-metal complexes. We find that simultaneous use 300 keV electrons, very low doses, and an ultrasensitive camera allows for collection data without cryogenic cooling stage. This technique reveals first crystal structures classic zirconocene hydride, colloquially known as "Schwartz's reagent", a novel Pd(II) complex not amenable solution-state NMR or X-ray crystallography, five other...
Electrochemical systems offer a versatile means for creating adaptive devices. However, the utility of electrochemical deposition is inherently limited by properties electrolyte. The development ionic liquids enables electrodeposition in high-vacuum environments and presents opportunities electrochemically regenerative spacecraft components. In this work, we developed silver-rich, boron cluster liquid (BCIL) reversible silver films. This air moisture stable electrolyte was used to deposit...
The synthesis and ethylene reactivity of the zwitterionic Pd methyl complexes (κ2-P,Cl-PR2CB9Cl9)PdMe(THF) (7, R = iPr; 8, Ph) (κ2-P,O-P(o-OMe-Ph)2CB9Cl9)PdMe(THF) (9), which contain first phosphines appended with anionic 10-vertex perchlorinated closo-carboranes, are described. Complexes 7 8 oligomerize (23 °C, 2 atm) to a Schulz–Flory distribution C4–C10 olefins TOFs ca. 8000 1800 t.o./h, respectively. is 4 times more active than analogous (κ2-P,F-ortho-PPh2C6H4BF3)PdMe(L) (L pyridine or...
In 1994 Reed and co‐workers reported a variety of trityl salts with various functionalized icosahedral carborane anions. However, it was mentioned that the parent carba‐ closo ‐dodecaborate anion [HCB 11 H ] – underwent an unidentified chemical reaction cation as ion pair formed in solution. this communication, we have reexamined identified classical electrophilic substitution B–H bond to afford new B‐arylated compounds, not dimer previously proposed. This is first example arylation anion....
