?-Arene clusters of cobalt and ruthenium on the base of biphenyl
Kaganovich, V. S.,Kerzina, Z. A.,Rybinskay, M. I.
, (1993)
For the first time monocluster ?-arene derivatives of biphenyl Ph2Co4(CO)9 and Ph2Ru6C(CO)14, the shared mononuclear monocluster complex Ph2Cr(CO)3Co4(CO)9, and the bicluster derivative of cobalt Ph22 have been synthesized.IR and 1H NMR spectra
Palladium catalysed cross-coupling of (fluoroarene)tricarbonyl-chromium(o) complexes
Wilhelm, Rene,Widdowson, David A.

(Fluoroarene)tricarbonylchromium(o) complexes were found to undergo Suzuki and Stille cross-coupling reactions to form functionalised biaryl and styrene complexes in up to 87 and 52% yields, respectively. The Suzuki reactions were optimal with dipalladium tris(dibenzylideneacetone)-trimethylphosphine-caesium carbonate in DME at reflux. The Stille reactions were optimal with dipalladium tris(dibenzylideneacetone)-trimethylphosphine-caesium fluoride in DME at reflux and neither was adversely affected by a methoxy group on the complexed ring. The Suzuki reaction tolerated a chloro group on the arylboronic acid ring but not a bromo group. The Royal Society of Chemistry 2000.
Electrophilic Substitution in (Arene)tricarbonylchromium Complexes. Part 1.
von Rosenberg, Joseph L.,Pinder, A. Reginald
, p. 747 - 752 (2007/10/02)
The Friedel-Crafts acetylation of several (arene)tricarbonylchromium complexes have been investigated.From the results it is concluded that the tricarbonylchromium group deactivates to a small extent towards electrophilic substitution the ring to which it is attached.In the case of tricarbonyl(diphenylmethane)chromium (1; n=1), however, attack occurred on both rings to about an equal extent, possible explanations for this unexpected behaviour are advanced.
