151. Azidinium-Salze. 24. Mitteilung. Thermolyse heterocyclischer Azidinium-tetrafluoroborate
Huys-Francotte, Martine,Balli, Heinz
, p. 1679 - 1684 (2007/10/02)
The thermolysis of some azidinium salts was investigated.It led to a large variety of products which were isolated or identified by GC/MS.Reaction mechanisms are discussed to explain the product formation.
REACTIONS OF POLYMETHINE DYES. I. SYNTHESIS OF THE PSEUDOBASES OF POLYMETHINE DYES AND THEIR TRANSFORMATIONS
Vompe, A. F.,Ivanova, L. V.,Meskhi, L. M.,Monich, N. V.,Raikhina, R. D.
, p. 529 - 537 (2007/10/02)
Nonsalt-like benzene-soluble pseudobases are formed in the reaction of polymethine dyes with sodium alcoholates.The presence of ionized and un-ionized forms of the pseudobases was established by electronic absorption spectra in aprotic solvents.Solutions of these compounds in alcohols only contain the ionized forms; the unionized form predominates in benzene solutions.The action of various acids on the pseudobases leads to the production of polymethine dyes with the respective anions.
Dication Ethers and Related Compounds, 1. On Dication Chalkogenides and Dichalkogenides
Maas, Gerhard,Singer, Berndt
, p. 3659 - 3674 (2007/10/02)
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.
