Functionalizing the surface of II–VI clusters: redox active centres on the adamantoid complex [Cd₄Cl₄{μ-(SeC₅H₄)Fe(C₅H₅)}₆]²⁻

Abstract

Trimethylsilylselenoferrocene 1 has been prepared in good yield. The reactive silyl group on 1 is used as a driving force for the synthesis [Cl4Cd4[mu2-Se(C5H4)Fe(C5H5))6]2- 2, a Cd4Se6 adamantoid cluster with six surface ferrocenyl groups.

Synthesis and reactivity of cyclopentadienyl ruthenium complexes containing ferrocenylselenolates

“…In contrast to most of the reactions of the chalcogens with metal chlorides [20][21][22], the treatment of CpRu(PPh 3 ) 2 Cl (2) with two equivalents of bis(trimethylsilylseleno)ferrocene (1) [Fc(SeSiMe 3 ) 2 ] did not lead to the formation of the desired products (Eq. 1).…”

“…Ferrocenylselenolate complexes can be prepared by the metathesis reaction of an alkali metal-selenolate salt [8][9][10][11][12][13], via chalcogenolysis cleavage of a Se-H bond [14,15] or by oxidative addition of diferrocenyldiselenide [16][17][18][19], as well as by reactions between trimethylsilyl(ferrocenyl)selenides and metals with a suitable leaving group such as a halide or an acetate ligand [20][21][22].…”

Synthesis, characterization and electrochemistry of ferrocenylselenolate bridged palladium(II) and platinum(II) complexes

“…These reactions are driven by the formation of the thermodynamically stable, soluble silane (Eq. (1)) [14,15].…”

Alk‐2‐ynyl Trimethylsilyl Chalcogenoethers by Nucleophilic Substitution of Propargyl Bromides

“…For the elements Se and Te, this typically involves silylation reactions of salts RE-M [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] (M = Li, Na) or REMgX (X = Cl, Br) with ClSiMe 3 . [30][31][32][33] Segi and co-workers have reported a general route to asymmetric thio-and selenoethers by the in situ generation of Me 3 SiE -nucleophiles from the silylated chalcogenides E(SiMe 3 ) 2 and alkyllithium reagents (Scheme 1).…”
