The core of the matter – arene substitution determines the coordination and catalytic behaviour of tris(1-phosphanyl-1′-ferrocenylene)arene gold(i) complexes

Abstract

Changing the aromatic core of C3-symmetric tris(ferrocenyl)arene-based tris-phosphanes has profound effects on their coordination behaviour towards gold(I). Depending on the arene (s-triazine, benzene, or trifluorobenzene), four different coordination modes can...

Ferrocenyl Gold Complexes as Efficient Catalysts

“…Hey-Hawkins and coworkers prepared interesting trinuclear gold(I) complexes with C3-symmetric trisphosphanes (Figure 5). [33,34] Although the complexes showed scarce values of activity in the absence of oxidant, complex 48a was finally successful as catalyst in a redox-switchable process, adding different equivalents of 1,1'-diacetylferrocenium tetrakis-(perfluo-tert-butoxy)aluminate [fc'Ac 2 ](TEF) as oxidant to switch on the process, and decamethylferrocene as a reductant to turn off the activity of the active species.…”

Homotrinuclear ruthenium(ii) and rhodium(i) complexes of redox-active tris(ferrocenyl)arene-based tris-phosphanes

“…Thus, tris-phosphanes 1a-d were employed in the formation of mono-and trinuclear gold(I) complexes, and the latter were shown to act as four-state redox-switchable catalysts. [30][31][32] We have now extended this synthetic concept to homotrinuclear rhodium(I) and ruthenium(II) complexes.…”

Comparison of crystal structure and DFT calculation of triferrocenyl trithiophosphite’s conformation

“…Design of novel "stimuli-responsive" molecules is very attractive area in modern chemistry due to a number of various practical applications of such compounds [1][2][3][4][5][6].…”
