34. 2 in MCH, the solution immediately became green-blue and then slowly turned brown; no pure product could be crystallized from it. The experimental conditions thus appear crucial to avoid decomposition. We have to conclude that the compound isolated by Evans et al. does not result from reaction with CO alone.

37. 2Yb is apparently precipitated from solution and thus not available for CO uptake; at higher temperatures, CO is lost under partial formation of the monocarbonyl complex.
