37. 2 as described above, and the mixture was stirred for 12 h. Upon concentration of the reaction mixture filtrate to 30 mL, a large first crop of reasonably pure 3a was recovered by filtration, provided filtration was performed quickly. The mother liquor was rotavapped to dryness, redissolved in toluene (150 mL), and filtered. After concentration in vacuo and cooling, three crops were collected: total 2.19 g (80% yield). Recrystallization from toluene is necessary to obtain 3a in high purity (c) For the corresponding chemistry with Cp sources, see: Niemann, J.; Teuben, J. H.; Huffmann, J. C.; Caulton, K. G. J.
