• Wittig reaction followed by reduction with DIBAL-H has been used as a route to allylic alcohols. See, e.g.: J. Org. Chem., 47, 1373 (1982).
• Stable ylide, which undergoes Wittig olefination with aldehydes, but not usually with ketones, to give enals: J. Chem. Soc., 1266 (1961); Angew. Chem. Int. Ed., 14, 486 (1975); Tetrahedron Lett., 3071 (1977). See Appendix 1. Reaction with aldehydes generally gives the thermodynamically more stable (E)-enal. Thus glyoxal gives trans,trans-muconic dialdehyde [(E),(E)-2,4-hexadienal]: Chem. Ber., 107, 710 (1974). The following sequence leads to (Z)-enals: Chem. Ber., 115, 161 (1982):
