Sulfide ion transfer from a vicinal dithiolate. A new route for the synthesis of mesocyclic trithiaethers
摘要:
Four mesocyclic and one macrocyclic trithiaethers have been synthesized using a sulfide ion transfer from a vicinal dithiolate. The mechanism of the sulfide ion transfer is discussed. An improved method for synthesizing 2-hydroxymethyl- 1,4,8,11-tetrathiacyclotetradecane is also reported. (c) 2005 Elsevier Ltd. All rights reserved.

[Pd(11S3-147)2]2+ does not display the unusual spectroscopic and electrochemical properties observed in smaller ring Pd(II) complexes. Its absorption spectrum does not show any d–d transitions and an irreversible ligand-centered oxidation is observed. A conformationalanalysisstudy for both macrocycles showed that neither has a lowest energy conformation suitable for tridentate coordination. The effects of the lack
