摘要：

Heat alone has been found sufficient to promote intramolecular Pauson-Khand cyclizations catalyzed by high purity Co-2(CO)(8). The existence of a very narrow thermal window (e.g., 60 degrees C - 70 degrees C) for the attainment of efficient catalysis is a noteworthy characteristic of this process.
