Silylation of Pyridine, Picolines, and Quinoline with a Zinc Catalyst [PDF]
ACS Omega, 2020 Zn(OTf)2 (OTf– = trifluoromethanesulfonate) catalyzes the silylation of pyridine, 3-picoline, and quinoline to afford the silylated products, where the silyl groups are meta to the nitrogen. The isolated yields of the products range from 41 to 26%.

Chromium picolinate, zinc picolinate and zinc picolinate dihydrate added for nutritional purposes in food supplements [PDF]
EFSA Journal, 2009 The Panel also noted that, although the safety of zinc itself, in terms of amounts that may be consumed, is outside the remit of this Panel, at the 97.5th percentile the dietary zinc intake from total food only is already close to the UL, as established by the SCF.

Selective enclathration of picolines [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 2004 The host 1,1,2,2-tetraphenyl-1,2-ethane diol has been employed to separate the isomers 2-picoline (2-pic), 3-picoline (3-pic), and 4-picoline (4-pic) by selective enclathration. The crystal structures are all stabilized by (host)-O−H···N(guest) hydrogen bonds. The competition experiments show that enclathration preferentially takes place in the order 4-
