TBADT‐Mediated C‐C Bond Formation Exploiting Aryl Aldehydes in a Photochemical Flow Reactor

ChemCatChem, Volume 15, Issue 2, January 20, 2023., 2023
Scaled Photochemical Reactions: A continuous flow approach for the photochemical synthesis of β‐ketonitriles and related species is presented. This approach tolerates (hetero)aromatic substrates and uses readily available TBADT as an effective HAT catalyst reaching throughputs of up to 41 mmol/h.

Foto‐Induzierte Ruthenium‐Katalysierte Doppel C(sp2)−H/C(sp3)−H Funktionalisierungen durch Radikalübertragungen

Angewandte Chemie, Volume 134, Issue 32, August 8, 2022., 2022
Die Ruthenium‐katalysierten doppelten distalen C(sp2)−H/C(sp3)−H‐Funktionalisierungen über Radikalübertragungen wurden durch milde Photokatalyse mit sichtbarem Licht ohne exogenen Photokatalysator erreicht, wobei meta‐Aren‐ und Wasserstoffatomtransfer (HAT)‐Funktionalisierungen mit einem einzigen Katalysator gezeigt wurden.

Hat-P-20b-Hat-p-23b: Four Massive Transiting Extrasolar Planets [PDF]

, 2011
We report the discovery of four relatively massive (2-7 M J) transiting extrasolar planets. HAT-P-20b orbits the moderately bright V = 11.339 K3 dwarf star GSC 1910-00239 on a circular orbit, with a period P = 2.875317 ± 0.000004 days, transit epoch T_c =

HAT-P-56b: An inflated massive Hot Jupiter transiting a bright F star followed up with K2 Campaign 0 observations [PDF]

, 2015
We report the discovery of HAT-P-56b by the HATNet survey, an inflated hot Jupiter transiting a bright F type star in Field 0 of NASA's K2 mission. We combine ground-based discovery and follow-up light curves with high precision photometry from K2, as ...

Paramyxoviruses activation by host proteases in cultures of normal and cancer cells

Вопросы вирусологии, 2017
Multiplication of paramyxovirus Sendai and Newcastle disease virus (NDV) was studied in cultures of normal and tumor cells. Production of noninfectious virus with uncleaved F0 was observed in canine kidney cell line MDCK (line H) and its derivatives ...

The TAFs in the HAT [PDF]

Cell, 1998
The striking phenomenon of histone acetylases with histone-like substructures that play critical (though distinct) roles in eukaryotic gene regulation raises evolutionary questions. We propose the following speculative scenario that begins with an Archea-like organism containing TBP and histones lacking N-terminal tails.
