N2 - The reaction of dicarbonyl- and carbonyl(trimethylphosphine)(cyclopentadienyl)-carbyne complexes of molybdenum and tungsten η5-C5H5(CO)2-n(PMe3)nMCR (n = 0, 1; M = Mo, W; R = CH3, C6H5, C6H4CH3, C3H5) with protic nucleophiles HX (X = Cl, CF3COO, CCl3COO) leads, through a combined protonation/carbon-carbon coupling reaction, to η2-acyl complexes η5-C5H5(CO)1-nX2(PMe3)n-M(η2-COCH2R). The reaction conditions, the results of the spectroscopic measurements and the X-ray structure of η5-C5H5(CO)(Cl2)W(η2-COCH2CH3) are reported.
