Abstract
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.
