Boenigk, Winfried,Haegele, Gerhard
, p. 2418 - 2425 (2007/10/02)
Reactions of pentafluoropyridine (8) and pentachloropyridine (15) with trialkylphosphite 2 led to dialkyl 2,3,5,6-tetrahalo-4-pyridylphosphonate (9 and 16, resp.).Formation and decay of an intermediate phosphorane C5F4NPF(OEt)3 (10) are discussed. 19F and 31P NMR data are reported.
