Synthesis, Characterisation of (Arene)tricarbonylchromium Complexes Linked to Cationic Fe and Ru Derivatives and Studies of First Hyperpolarisabilities by Hyper‐Rayleigh Scattering

European Journal of Inorganic Chemistry (2003)

Abstract In order to investigate the non‐linear optical properties, in particular second‐order effects of binuclear organometallic complexes, a series of new cationic binuclear [MCp(DPPE)N≡C−(spacer)−C≡C−C 6 H 5 Cr(CO) 3 ] + [PF 6 ] − compounds and mononuclear precursors [N≡C−(spacer)−C≡ C−C 6 H 5 Cr(CO) 3 ] have been synthesised [where M = Fe II or Ru II ; Cp = η 5 ‐C 5 H 5 and spacer = phenyl ring (C 6 H 4 ), thiophene, (C 4 H 2 S), or bithiophene (C 4 H 2 S) 2 ]. The Fe or Ru organometallic π‐donor fragments were linked by an extended π system to the acceptor Cr(CO) 3 fragment. The effect of π back‐donation involving the second Fe or Ru metal centre and the π* orbitals of the N≡C‐coordinated group, was probed by the ν (N≡C) stretching bands on the IR spectra and also by NMR spectroscopic data. The planarity, largely due to the π‐electron resonance, found on the solid state structure of the mononuclear complex [N≡C−C 6 H 5 −C≡C−(η 6 ‐C 6 H 5 )Cr(CO) 3 ] ( 1Cr ) determined by X‐ray diffraction [monoclinic system, P 2 1 / c space group, with a = 10.326(2) Å, b = 13.209(5) Å, c = 11.799(2) Å and Z = 4] emphasises the electronic effect of this building block. The significant values of first hyperpolarisability β determined by hyper‐Rayleigh scattering (HRS) indicate that the Fe containing compounds were more efficient on second‐order non‐linear optical properties than the ruthenium analogues and the parent mononuclear chromium compounds.

(η⁶-Arene)tricarbonylchromium and Ferrocene Complexes Linked to Binaphthyl Derivatives

Organometallics (2007)

R.F. Germaneau René Chavignon Jean‐Philippe Tranchier F. Rose‐Munch Éric Rose

Palladium-catalyzed coupling reactions of 6,6'-dihydroxyboron-2,2'-dimethoxy-1,1'-binaphthyl 5g and chloroarenetricarbonylchromium complexes 6a−c afforded complexes 7a−c with the binaphthyl residue directly linked to the (η6-arene)tricarbonylchromium entity. Coupling reactions of 2,2'-dimethoxy, 3,3'-diodo, and 6,6'-diodo-1,1'-binaphthyl 3h and 5h with ethynylarenetricarbonylchromium derivatives 6d−f and ethynylferrocene 9 yielded binaphthyl compounds linked to arenetricarbonylchromium and ferrocenyl derivatives 8a−c, 11a−c, 10, and 12 through a triple bond. Condensation of 2,2'-dimethylmethoxy, 3-formyl, 1,1'-binaphthyl 2a with (η6-phenyl)methyltriphenylphosphonium tricarbonylchromium 13 and ferrocenylmethyltriphenylphosphonium 18 gave binaphthyl compounds linked to arenetricarbonylchromium and ferrocenyl derivatives 14 and 19, respectively, through a double bond. X-ray analyses of the dinuclear chromium complex 8a and of the mononuclear chromium complex 17-Z are described.

Intervention by an η⁶-Organochromium Moiety Switches Chemoselectivity in Palladium-Catalyzed Reactions with Trialkyltin Compounds

Organometallics (2001)

Damien Prim Jean‐Philippe Tranchier René Chavignon F. Rose‐Munch Éric Rose

The reaction of (chloroarene)tricarbonylchromium with hexaalkylditin under palladium catalysis does not proceed by the expected Stille reaction with addition of an SnR3 group but, instead, affords alkylarene complexes via a postulated chromium-assisted alkyl migration.
