Syntheses and crystal structures of neutral tetrairon complexes with the unique SCPPh2S ligand

Abstract

The novel reactions of cluster salts [(μ-RS)Fe(2)(CO)(6)(μ(4)-CS(2))Fe(2)(CO)(6)][Et(3)NH] with Ph(2)PCl, via the insertion of the PPh(2) group into an activated C-S bond, afford the unprecedented tetrairon complexes with the unique SCPPh(2)S ligand which is coordinated to (μ-RS)Fe(2)(CO)(6) and Fe(2)(CO)(6) units in a μ(4)-k(2)C:k(4)S,S' mode (R = Ph, CH(3)O(2)CCH(2)).

Syntheses of new Fe/S clusters via reactions of Fe3(CO)12 and salts of heteroallyl anions of type [GCS2]− (G=Ph2PS, ArCOCH2, 2-C5H4NNH and 2-C3H2NSNH) with electrophiles

“…In view of no reports on heteroallyl anions of type G-C(@Y)-Z À (G = potential donor group; Y = S, Se; Z = S, Se, NR, CHR) with iron carbonyls, we have initiated the project on reactions of heteroallyl anions of type G-C(@Y)-Z À with iron carbonyls to develop the synthetic methodology of Fe cluster complexes. As part of the ongoing project, herein we report that reactions of Fe 3 (CO) 12 and salts of heteroallyl anions of type [GCS 2 ] À (G = Ph 2 PS, ArCOCH 2 , 2-C 5 H 4 NNH and 2-C 3 H 2 NSNH) with electrophiles [18,19].…”

Syntheses of Novel Fe/S Clusters with μ‐Aminocarbyne Ligands

“…Reactions of Fe 3 (CO) 12 and heteroallyl anion salt (C 3 H 5 ) 2 NCS 2 K with electrophiles have opened up a novel route to spiro-S Fe/S clusters with aminocarbyne ligands. Reactions of other heteroallyl anions of type G-C(=Y)-Z -(G = potential donor group; Y = S, Se; Z = S, Se, NR, CHR) with iron carbonyls and with electrophiles are under investigation.…”

“…1 is an e-type isomer. [12] Two planes of S1Fe1Fe2 and C13Fe1Fe2 form a dihedral angle of 75.83(15)°. The S1Fe1Fe2 plane with the S1Fe3Fe4 plane makes a dihedral angle of 85.…”

“…A 100-mL Schlenk flask equipped with a stir bar and serum cap was charged with Fe 3 (CO) 12 (1.007 g, 2 mmol), (C 3 H 5 ) 2 NCS 2 K (0.423 g, 2 mmol), and THF (30 mL). The mixture was stirred for 3 h at room temperature to form a red-brown solution.…”

“…In order to develop the synthetic methodology of Fe/S cluster complexes for model compounds, we have recently initiated the project on reactions of heteroallyl anions G-C(=Y)-Z -(G = potential donor group; Y = S, Se; Z = S, Se, NR, CHR) with iron carbonyls. [12][13][14][15][16] As part of the on-going project, in this article we report the syntheses of novel Fe/S clusters via reactions of Fe 3 (CO) 12 and (C 3 H 5 ) 2 NCS 2 K with electrophiles.…”
