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.
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.
