title: Unexpected formation of a cyclopentadienylruthenium alkoxycarbonyl complex with a coordinated C=C bond.
abstract: Reaction of (eta(5)-Ph(5)C(5))Ru(CO)(2)(Ot-Bu) with 5-hexen-2-ol produces two diastereomers of an alkoxycarbonyl complex having the double bond coordinated to ruthenium. The complexes were characterized by (1)H and (13)C NMR spectroscopy and in situ FT-IR measurements. The (13)C NMR carbonyl peaks of the complexes appear at 203.48, 203.55, and 204.0 ppm in a ratio of 1:1:2. IR peaks for CO and acyl were detected at 1982 (CO) and 1644 (acyl) cm(-1).
