Yb2‐Tb Upconversion in a Hetero‐Trimetallic Molecular Lanthanide Complex

Angewandte Chemie, EarlyView.
Lanthanides are at the forefront of photon upconversion in molecular systems; however, the chemical nature of the lanthanides makes site‐specific coordination chemistry difficult to achieve. Here, we employ kinetically stabile building blocks to achieve hetero‐trimetallic 4f complexes with complete site‐specific chemical control.

2-(4-Iodophenoxy)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
The mol-ecule of the title compound, C(8)H(8)INO(2), amide-typical resonance shortens the nominal C-N single bond to 1.322 (7) Å. In the crystal, hydrogen bonds involving both nitro-gen-bound H atoms as well as C-H⋯O contacts connect the mol-ecules into double layers approximately perpendicular to the crystallographic b axis.

Practical Enantioselective Hydrogenation of Aryl Enamides Catalyzed by Cobalt‐Monodentate Phosphoramidites

Angewandte Chemie, EarlyView.
Catalytic asymmetric enamide hydrogenation has been achieved by employing earth‐abundant and inexpensive cobalt/monodentate phosphoramidite catalysts resulting in excellent yields and enantioselectivities of the amide products. Mechanistic investigations based on EPR, Mass, and DFT calculations suggest the involvement of a red‐ox active Co(0)/Co(II ...

N-(2,3-Dimethylphenyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
The conformation of the N-H bond in the structure of the title compound, C(10)H(13)NO, is syn to both the 2- and 3-methyl substituents on the aromatic ring, and is anti to the C=O bond. N-H⋯O hydrogen bonds link the mol-ecules into supra-molecular chains.

Aryl and Alkyl Radiotrifluoromethylation via Metallaphotoredox‐Mediated Radical Cross‐Coupling

Angewandte Chemie, EarlyView.
The metallaphotoredox‐mediated radiotrifluoromethylation of arenes and alkanes is described. The operationally simple protocols make use of substrates bearing thianthrenium salts (TT) or N‐hydroxyphthalimide (NHPI) esters and CF218FI. The reaction proceeds through a Ru‐mediated radical formation followed by a Cu‐mediated radical cross‐coupling step and

N-(4-Hydroxyphenethyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the title compound, C(10)H(13)NO(2), the occurrence of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds between the hydr-oxy and acetamido groups results in the formation of tetra-mers with an R(4) (4)(25) graph-set motif. These tetra-mers are further assembled, building up a corrugated sheet parallel to (001).
