Mechanistic investigations of the formation of TTF derivatives via the phosphonate way

We studied the influence of acetic acid concentration on the deamination and dephogphonylation of the adduct resulting of the nucleophilic reaction between adequate α-metalated phosphonate and imminium salt, to enhance the yield of such reactions in order to access efficiently a lot of unsymmetrical TTF derivatives. A mechanism is proposed for the formation of TTF, including steps, i1 to i7. The potential concurrent formation of phosphonate 1 and other by-products is also discussed.

Dication Ethers and Related Compounds, 1. On Dication Chalkogenides and Dichalkogenides

Reaction of N,N-, N,S-, S,S-, and O,O-substituted thiones 4a-f or selones 6a-c with trifluoromethanesulfonic anhydride leads to dication disulfides 5a-f or diselenides 7a-c, resp.No dication sulfides or selenides are obtained whose formation would parallel the reactivity of the corresponding urea derivatives.This class of dications (14, 15) is, on the other hand, accessible by the reaction of dication ethers 13 with thiones 4 or selones 6. 1H and 13C NMR data of the dication dichalkogenides and chalkogenides are compared with each other.
