THE NUCLEOPHILIC ATTACK OF A VINYL-HALO-PHOSPHINE BY A TERTIARY AMINE: A NEW ACCESS TO PHOSPHAALKENES
Mercier, F,Mathey, F.
, p. 5269 - 5270 (2007/10/02)
The reaction of DABCO with (2,4,6-tris-tertiobutylphenyl)(vinyl) halo phosphine (X=Cl, Br) yields the corresponding 1-(2,4,6-tris-tertiobutylphenyl)-2-ammoniomethyl phosphaethene via a SN2'-like attack at the vinylic CH2.
