Literature References

Forms a moderately stable crystalline ylide which reacts with aldehydes to give ɑß-unsaturated nitriles, predominantly as their (Z)-isomers: Chem. Ber., 94, 578 (1961); J. Chem. Soc., 1266 (1961); Appendix 1.

/n

Further deprotonation of the phosphorane with sodium bis(trimethylsilyl)amide followed by C-alkylation generates a homologated phosphorane: Angew. Chem. Int. Ed., 26, 79 (1987).

/n

Reaction of the ylide with carboxylic acids in the presence of EDCI (1-(3-Dimethyl­aminopropyl)-3-ethyl­carbodiimide hydrochloride, A10807) and DMAP, followed by ozonolysis of the resulting acylphosphoranes, provides a novel route to the homologous ɑ-keto esters: J. Org. Chem., 59, 4364 (1994):
