Construction of a Functionalized Selenophene‐Allylidene Ligand via Alkyne Double Action at a Diiron Complex

Abstract: The diiron µ‐vinyliminium compounds [Fe2Cp2(CO)(µ‐CO){µ‐η1:η3‐C3HC2HC1NMe(R)}]CF3SO3 (R = Me, 2a; R = Xyl = 2,6‐C6H3Me2, 2b; Cp = η5‐C5H5) reacted with grey selenium, in the presence of sodium methoxide, to give the corresponding Se‐functionalized derivatives [Fe2Cp2(CO)(µ‐CO){µ‐η1:η3‐C3HC2(Se)C1NMe(R)}], 3a–b, in ca. 50 % yields. The monoiron zwitterionic complex [FeCp(CO){SeC1(NMe2)C2HC3H}], 4, was obtained as a side‐product (31 %) of the reaction leading to 3a. The treatment of 3b with S8/NaOMe afforded the… Show more

“…[1][2][3] For instance, as two working hands compared to one single hand, dimetallic systems offer major opportunities to build and stabilize uncommon hydrocarbyl ligands via multisite bridging coordination. [4][5][6][7][8][9][10] Alkynes are useful and versatile reagents in this setting, and in particular the {M 2 Cp 2 (CO) x } scaffold (M = Fe, Ru; Cp = η 5 -C 5 H 5 ; x = 2, 3) is suitable to promote their coupling with a diversity of bridging coordinated carbon ligands, including carbonyl, 11,12 isocyanide, 13 thiocarbonyl, 14 alkylidyne 10,15,16 and alkylidene ligands, [17][18][19][20] usually via alkyne insertion into the metal-μ-carbon bond, but alternative modes are also possible. 21 The two metal coordination spheres are coordinatively and electronically saturated, therefore prior removal of one 2-electron ligand (usually, a carbon monoxide ligand) is needed to guarantee the initial η 2 -coordination of the alkyne to one metal centre, that is a preliminary, fundamental step along the coupling process.…”

“…The synthesis and characterization of [ 2a – d ]­CF 3 SO 3 , 3a – c , and 4a – j are reported in the Supporting Information. Compounds [ 1 ]­CF 3 SO 3 and 3d were prepared according to published procedures. Organic reactants (TCI Europe or Merck) and [Fe 2 Cp 2 (CO) 4 ] (Strem) were commercial products of the highest purity available.…”
