Synthesis and characterization of a silver(I) triflate sandwich complex of 1,2:5,6:9,10-tribenzocyclododeca-1,5,9-triene-3,7,11-triyne. The first example of a 12-membered macrocycle sandwich complex

Abstract

CF3SO3Ag reacts with the macrocyclic triyne ligand in THF in different ratios within several days to give the title complex (I) (yield 5‐10%) and polymerized THF.

Homoleptic Silver(I) Acetylene Complexes

“…18–21 Herein, we used the pseudo‐gas‐phase conditions induced by the [Al(OR F ) 4 ] − anions to stabilize salts of the [Ag(η 2 ‐C 2 H 2 ) n ] + ( n =1, 3, 4) cations. The parent compounds of all homoleptic [M(C 2 H 2 ) x ] n complexes (M=any metal; n , x =any number) are to date unknown in condensed phases 22–26. The exceptional stability of the [Ag(C 2 H 2 )] model complex allowed us to analyze the fine structure of the charge‐density distribution inside the valence shell of the silver atom by high‐resolution X‐ray diffraction at 10 K. This topological analysis provides the first experimental insight into the microscopic nature of acetylene fixation at a metal center.…”
