“…Consistent with -the covalent radii of Mn and Re, the Mn–Te bond length of fac - 2 (2.599(1) Å) and 3 (2.546(1) Å) are smaller than the Re–Te bond length of fac - 1 (2.733(1) Å). The Mn–Te distances are in between values reported for [Mn(CO) 4 TePh] 2 (mean 2.674(2) Å) [ 15 , 16 , 17 ] and [Cp′(CO) 2 Mn] 2 TeMes + (2.44 Å) [ 18 ].…”

Bis(6-Diphenylphosphinoacenaphth-5-yl)Telluride as a Ligand toward Manganese and Rhenium Carbonyls

The reaction of the previously known bis(6-diphenylphosphinoacenaphthyl-5-)telluride (6-Ph2P-Ace-5-)2Te (IV) with (CO)5ReCl and (CO)5MnBr proceeded with the liberation of CO and provided fac-(6-Ph2P-Ace-5-)2TeM(X)(CO)3 (fac-1: M = Re, X = Cl; fac-2: M = Mn, X = Br), in which IV acts as bidentate ligand. In solution, fac-1 and fac-2 are engaged in a reversible equilibrium with mer-(6-Ph2P-Ace-5-)2TeM(X)(CO)3 (mer-1: M = Re, X = Cl; mer-2: M = Mn, X = Br). Unlike fac-1, fac-2 is prone to release another equivalent of CO to give (6-Ph2P-Ace-5-)2TeMn(Br)(CO)2 (3), in which IV serves as tridentate ligand.

“…Transition-metal–carbonyl compounds containing chalcogen atoms have attracted much attention in recent years, owing to their importance in fundamental research as well as in technological fields. – The presence of chalcogen atoms appears to often be decisive in cluster aggregation and condensation reactions. – In addition, interest in chalcogen-rich metal compounds stems from their unusual structural and reactivity patterns and application as precursors for new solid-state materials. , A potential route to prepare the chalcogenide carbonyl species is by the facile oxidative addition of Ph 3 PE (E = S, Se, Te) to zerovalent metal centers, which commonly generates tertiary phosphine substituted clusters with capping chalcogenide elements . Another method for the synthesis of bridging chalcogenide metal–carbonyl clusters involves the cleavage of E−E bonds of diphenyl dichalcogenide ligands . Applying this latter approach, Lewis et al and Arce et al synthesized the 50-electron cluster [Os 3 (CO) 10 (μ-SePh) 2 ], in which one SePh group bridged an Os−Os edge and the other an open Os−Os edge, from the reactions of [Os 3 (CO) 12- n (NCMe) n ] with PhSeSePh.…”

Reactions of [Ru 3 (CO) 10 (µ-dppm)] (1) and its ortho-metalated derivative [Ru 3 (CO) 9 {µ 3 -η 3 -P(C 6 H 5 )CH 2 P(C 6 H 5 )(C 6 H 4 )}] (11) with PhEEPh (E ) Te, Se, S) have been investigated. Treatment of 1 with PhTeTePh at room temperature afforded the dinuclear compound [Ru 2 (CO) 4 (µ-TePh) 2 (µ-dppm)] (2) and the 54-electron triruthenium compounds [Ru 3 (CO) 6 (µ 3 -Te) 2 (µ-TePh) 2 (µ-dppm)] (3) and [Ru 3 (CO) 6 (µ 3 -Te)(µ-TePh) 3 (η 1 -COPh)(µ-dppm)] (4). Analogous reactions of 1 with PhEEPh (E ) Se, S) led to [Ru 2 (CO) 8) and the 54-electron triruthenium compounds (E ) Se, 6; E ) S, 9), and [Ru 3 (CO) 6 (µ 3 -E)(µ-EPh) 3 (Ph)(µ-dppm)] (E ) Se, 7; E ) S, 10). Reactions of the ortho-metalated complex 11 with PhEEPh (E ) Te, Se, S) in refluxing THF gave exclusively [Ru 3 (CO) 6 (µ-EPh) 2 {µ 3 -η 3 -P(C 6 H 5 )CH 2 P(C 6 H 5 )(C 6 H 4 )}] (E ) Te, 12; E ) Se, 13; E ) S, 14). The new compounds have been characterized by a combination of analytical and spectroscopic methods, and molecular structures of 2-4, 7, 10, and 13 have been determined by single-crystal X-ray diffraction studies. Compounds 2, 5, and 8 have the classical "sawhorse" structure with two bridging EPh (E ) Te, Se, S) moieties and one bridging dppm ligand. Compounds 3, 6, and 9 contain a Ru 3 framework with two bridging EPh (E ) Te, Se, S) groups, one bridging dppm ligand, and two capping chalcogenido ligands. Compound 4 contains an Ru 3 core with a capping tellurido ligand, three bridging TePh moieties, one bridging dppm ligand, and a terminally coordinated benzoyl group, formed from multiple fragmentation of the PhTeTePh ligand and migratory insertion of a Ph group into a CO ligand. Compounds 7 and 10 comprise a capping chalcogenido ligand, three bridging EPh (E ) Se, 7; E ) S, 10) moieties, a bridging dppm ligand, and a terminally coordinated σ-bonded phenyl group. In compounds 12-14, the coordination of ortho-metalated diphosphine ligand is the same as in 11 and both the EPh moieties bridge the same unbridged Ru-Ru edge. Compounds 3, 6, 7, and 10 exhibit restricted fluxional behavior involving the µ-EPh moieties.

“…In our further communications [9][10][11][12][13] we reported syntheses of a variety of analogous dicarbonyl rhodium(I) complexes with bidentate monoanionic ligands and salts of the [Rh(CO) 2 Cl 2 ] À anion. Within the following four decades this method has gained wide acceptance and has become a routine laboratory practice (see for example [14][15][16][17][18][19][20][21][22][23][24][25][26]) and a subject of industrially oriented studies [27]. The mechanistic scheme we suggested [28,29] involved direct carbonyl group transfer from a DMF molecule to a rhodium atom.…”
