Heterophane mit 1,3,5-Triazinbausteinen und Thiol/Disulfid-Redoxschalter
摘要:
The synthesis and characterization of 5 new coronands 2a-e, containing two 1,3,5-triazine-thiols as subunits and redox-switch are described. Cryptands 3a-e with disulfide bridges were obtained by oxidation. Reduction of cryptands 3a-e yields back the coronands 2a-e. The different complexation properties of the macrocycles 2a-d and 3a-d toward TI(I), Ag(I) and Hg(II) are also reported.

The synthesis and characterization of 10 new cryptands 5a-j, containing two 1,3,5-triazine rings as subunits are described. The general methodology used is based on the aminolysis of cyanuric chloride with alpha,omega-diamino compounds or diazacrowns.
