(η6-1,4-(CH3SO3)2C6H4)Cr(CO)3: synthesis, characterization, and reactivity

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.
