The easily accessible pyridines 10 are transformed into sodium salts 12a-c by reaction with sodium bis(trimethylsilyl)amide (11).With electrophiles 13, the salts 12 usually react to give N-substituted 4-alkylidene-1,4-dihydropyridines 5a-f.This reaction b
phosphonium Salts, 4: Synthetic Methods

, p. 124 - 131 (2007/10/02)
Four syntheses A - D are described for the phosphonium salts 1, which are precursors of the highly reactive phosphoranes 3.Whereas the usual method B fails in some cases it is now possible to prepare 1 with a wide variety of substituents R1, R
