| Abstract: | Conclusions The formation of 2,4,6-trifluoro-3,5-dichloropyridine by the reaction of pentachloropyridine with KF in MeCN, in the presence of catalytic amounts of an 18-crown 6-ester, proceeds at considerably lower temperatures and is not complicated by the presence of the reverse reaction.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 949–950, April, 1978. |
