An Efficient Synthesis of (Fluoromethyl)pyridylamines for Labeling with Fluorine-18

, 2016
We have described a two-step method for the preparation of (fluoromethyl)pyridyl-substituted amines. The sequence involves fluoride ion displacement of methanesulfonates (mesylates) of 6-chloro-α-hydroxy-2- and -3-picolines, followed by arylation of the ...

Structure features and thermochemistry of the intercalation of pyridine and alpha-, beta-, and gamma-picolines into crystalline alpha-titanium hydrogen phosphate

, 2015
The insertion of polar organic molecules inside the gallery space of the synthetic crystalline lamellar alpha-titanium hydrogen phosphate was followed by a batch method at 298 +/- 1 K. The maximum amounts intercalated were 3.34, 1.54, 1.85, and 2.21 mmol
