SYNTHESIS OF 2-(2'-HYDROXYPHENYL)PYRIDINE-N-OXIDE AND ITS THERMAL DECOMPOSITION AS A MODEL REACTION OF ORELLANINE DEOXIDATION
Antkowiak, Wieslaw Z.,Gessner, Wieslaw P.
, p. 4045 - 4048 (1984)
2-Methoxyphenylmagnesium bromide was reacted with 2-nitropyridine-N-oxide and demethylated to give 2-(2'-hydroxyphenyl)pyridine-N-oxide (II) which was found to undergo a thermal deoxidation to the free base (VI); the process is interpreted as a oxygen shift followed by decomposition of the hydroperoxide intermediate.
Copper(II) Catalyzed C–H Alkoxylation of 2-Phenyl Pyridines with Aliphatic Diols
Xiao, Yan,Li, Juan,Liu, Yajun,Wang, Shuo,Zhang, Hui,Ding, Huaiwei
, p. 3306 - 3311 (2018)
A very simple copper(II) catalyzed C–O coupling reaction of 2-phenylpyridines and aliphatic diols was achieved by using a strategy of C–H functionalization. A series of aroxyl ethanols are easily obtained with the yields of 30–67 %. Various functional groups, as well as different length of aliphatic diols are well tolerated in the developed catalytic system. This new protocol featurs a simple reaction system, economical catalyst and good regioselectivity. In addition, a “one-pot” synthesis of 2-phenyl pyridines was developed.
Amination of the ortho C-H bonds by the Cu(OAc)2-mediated reaction of 2-phenylpyridines with anilines
Uemura, Takeshi,Imoto, Shinya,Chatani, Naoto
, p. 842 - 843 (2006)
The reaction of 2-phenylpyridines with anilines in the presence of Cu(OAc)2 as a promoter results in selective mono-amination of the ortho C-H bonds in 2-phenylpyridines to give amine derivatives in high yields per the conversion. This is the r
The Co-ordination Chemistry of Mixed Pyridine-Phenol Ligands; Spectroscopic and Redox Properties of Mononuclear Ruthenium Complexes with (Pyridine)6-x(Phenolate)x Donor Sets (x = 1 or 2)

, p. 3345 - 3352 (1992)
Two new ruthenium complexes containing N5O and N4O2 donor sets (where N is a pyridyl donor and O a phenolate donor) were prepared, in order to study the electrochemical and spectroscopic consequences for the ruthenium centre of stepwise replacement of pyr

Mixed ligand cyclopalladated complexes with 2-phenylpyridine (ppy) and 2,9-dimethyl-1,10-phenanthroline (ncp), 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (bcp), 4,7-diphenyl-1,10-phenanthroline (bphen) were synthesized and characterized. The crystal st
Hydroxyphenyl-1-methylpyridinium-iodide as Potential Reactivators of Acetylcholinesterase Poisoned with Organophosphorus Compounds
Riggio, Gaetano,Hopff, Wolfgang Herbert,Hofmann, Alfred Andre,Waser, Peter Gaudenz
, p. 1039 - 1045 (1983)
It was our aim to reactivate acetylcholinesterase poisoned with sarin.We synthesized 2-(o-hydroxyphenyl)-1-methylpyridinium-iodide (9), 2-(p-hydroxyphenyl)-1-methylpyridinium-iodide (19) and 4-(o-hydroxyphenyl)-1-methylpyridinium-iodide (14) as potential reactivators.All substances showed moderate toxicity against mice; their reactivity potency in vitro and in vivo was negligible.

Chemoselective 18F-incorporation into pyridyl acyltrifluoroborates for rapid radiolabelling of peptides and proteins at room temperature
Chiotellis, Aristeidis,Ahmed, Hazem,Betzel, Thomas,Tanriver, Matthias,White, Christopher J.,Song, Haewon,Da Ros, Sara,Schibli, Roger,Bode, Jeffrey W.,Ametamey, Simon M.
, p. 723 - 726 (2020)
A new prosthetic group is reported for 18F-labelling of peptides and proteins based on the chemoselective ligation of potassium acyltrifluoroborates (KATs) and hydroxylamines without any detectable 18F/19F isotope exchange at the acyltrifluoroborate moiety. The new building block is appended via a common amide bond at room temperature with no need for protecting groups which enables an effective orthogonal 18F-radiolabelling.
