, p. 130 (2007/10/03)
We describe the first synthesis of new 1,1-diphenyl-2,5-dihydrophospholium salts of type 1.These salts allow the access to interesting alkadienyl phosphine oxides 3 and trienes 4.Unfortunately we could not obtain the strong nucleophilic diylide 5. - Keywords: Dihydrophospholium Salts, ylides, Wittig Reaction, Trienes.
SYNTHESIS AND REACTIVITY OF A NEW 1,1-DIPHENYL 2,5-DIHYDROPHOSPHOLIUM SALT
Cristau, H.-J.,Grenier, J.,Torreilles, E.
, p. 163 - 172 (2007/10/02)
We describe the first synthesis of an unsaturated cyclic diphenyl phosphoium salt of type 2, the 1,1-diphenyl 2,5-dihydrophospholium salt 2d.The method involves a cyclo-addition of the diphenyl halophosphine to the corresponding diene.The salt 2d allowed
