Application:	2,6-Difluoropyridine has been used in the preparation of poly(pyridine ether)s via polycondensation with silylated 1,1,1-tris(4-hydroxyphenyl)ethane.
General description:	Lithium diisopropylamide (LDA)-mediated ortholithiations of 2,6-difluoropyridine in tetrahydrofuran at -78°C has been studied using a combination of IR and NMR spectroscopic and computational methods. Polycondensation of bistrimethylsilyl derivatives of various diphenols with 2,6-difluoropyridine in N-methylpyrrolidone in the presence of K₂CO₃ has been investigated.
Packaging:	5, 25 g in glass bottle
