Cluster core growth upon the decarbonylation of cyclopentadienyl-iron-dicarbonyl ferrocenyltelluride CpFe(CO)2TeFc: Fe1Te1 to Fe3Te3

Iminium substituent directs cyanide and hydride additions to triiron vinyliminium complexes

“…It should be highlighted that only a limited number of compounds consisting of a diiron [CpFe I Fe I Cp] core conjugated with a ferrocenyl [Fe II ] unit through a bridging hydrocarbyl ligand have been reported to date. 35–37 With the aim of investigating these features, we studied the reactions of a series of triiron vinyliminium complexes, [1]CF 3 SO 3 , bearing different iminium R substituents, with cyanide and hydride sources. Here we present the results of our investigation, together with an extensive DFT study aimed to rationalize the reaction outcomes.…”

“…It should be highlighted that only a limited number of compounds consisting of a diiron [CpFe I Fe I Cp] core conjugated with a ferrocenyl [Fe II ] unit through a bridging hydrocarbyl ligand have been reported to date. [35][36][37] With the aim of investigating these features, we studied the reactions of Scheme 1 (A) Sequential synthesis of diiron complexes with bridging aminocarbyne and vinyliminium ligands, respectively (triflate salts); R = alkyl, aryl; R 0 = alkyl, aryl, H, SiMe 3 , CO 2 Me, pyridyl, thiophenyl. (B) Reactions of diiron m-vinyliminium complexes, derived from the assembly of isocyanide (CNR, red), alkyl (Me, green) and alkyne (R 0 CRCH, blue) units, with nucleophiles.…”
