supporting information; experimental part, p. 5313 - 5320 (2009/09/30)
A series of ruthenium olefin metathesis catalysts bearing N-heterocycliccarbene (NHC) ligands with varying degrees of backbone and N-aryl subst itution have been prepared. These complexes show greater resistance to decomposition through C-H activation of
Synthesis and complexation properties of poly(ethylene glycol)-linked mono- and bis-dioxocyclams
Puntener,Hellman,Kuester,Hegedus
, p. 8301 - 8306 (2007/10/03)
Both tri- and tetra(ethylene glycol) linked bis-chromium carbene complexes have been synthesized. These carbene complexes were photolyzed with N-protected imidazolines to give protected azapenams. These were transformed into polyether-linked basket dioxocyclams 4a,b and bis-dioxocyclams 5a,b. These compounds have cavities for the complexation of both 'hard' and 'soft' metal ions. The complexes of Ni, Ba, and Gd were synthesized.
