- Conjugate addition of organocuprates leads to a new phosphonium salt which can be used in the Wittig olefination. With alkenyl cuprates this provides a stereoselective route to (Z,Z)-1,4-pentadienes: Tetrahedron Lett., 26, 1799 (1985).

- Conjugate addition of organocuprates leads to a new phosphonium salt which can be used in the Wittig olefination. With alkenyl cuprates this provides a stereoselective route to (Z,Z)-1,4-pentadienes: Tetrahedron Lett., 26, 1799 (1985). Sequential reactions, catalyzed by CuBr - Ag2CO3 or CuBr - H2O, with Grignard reagents and Wittig olefination with an aldehyde, have also been reported: J. Org. Chem., 61, 9659 (1996):
- Conjugate additions of nucleophiles to the double bond give ß-substituted ethyl triphenylphosphonium salts which can be further reacted by Wittig olefination. Sequential reaction with phthalimide and an aldehyde leads, after hydrazinolysis of the resulting N-allylphthalimide, to 3-substituted allylamines: J. Org. Chem., 46, 3119 (1981). N-Alkyl allylamines can also be prepared from alkylamines: Tetrahedron Lett., 24, 3043 (1983):
