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.
Kronenether mit 1,3,5-Triazinen als Ringbaustein - Synthese und Untersuchung der Alkaliselektivit�t durch Elektrospray-Ionisations-Massenspektrometrie
摘要:
The synthesis and characterization of 5 new crown compounds 3 and some derivatives 4, containing a 1,3,5-triazine ring as subunit, based on the aminolysis of cyanuric chloride with diamines, is described. The alkali selectivity of some crown ligands were investigated by the ESI mass spectrometry.
