(η6-1,4-(CH3SO3)2C6H4)Cr(CO)3: synthesis, characterization, and reactivity
Wright, Michael E.
, p. 353 - 358 (1989)
Reaction of (MeCN)3Cr(CO)3 with hydroquinone in refluxing tetrahydrofuran (THF) produced (η6-1,4-C6H4(OH)2)Cr(CO)3 (1) which was subsequently converted to (η6-1,4-(CH3SO3)2C6H4)Cr(CO)3 (2) by treatment with methanesulfonyl chloride and triethylamine.A single-crystal X-ray study of 2 has been completed and is reported.Treatment of 2 with an oxygen nucleophile gave reaction at sulfur; whereas, treatment of 2 with lithium phenylacetylide resulted in decomposition of the complex to metallic chromium.
Dialkynylated and functionalized alkynylated areneCr(CO)3-complexes - Syntheses and structures of carbon rich chromium-complexed benzenes
Mueller, Thomas J.J.,Ansorge, Markus,Polborn, Kurt
, p. 252 - 259 (1999)
The dialkynylated η6-(arene)Cr(CO)3-complexes 2 and 4 can be synthesized: (a) by Sonogashira coupling of alkynes with dihalo areneCr(CO)3-complexes; or (b) very efficiently by a Horner-Emmons-Wadsworth related acetylene synthesis with readily available Cr(CO)3-complexed aryl aldehydes. The structural constitution of two novel difunctional alkynyl arene complexes (2a and 6) was confirmed by X-ray crystal structure analyses.
