摘要

The pyrolysis of the vinyldiazomethanes 6 (X= H), 8, 9, and 10 gives mixtures of 3H- pyrazoles and cyclopropenes. The kinetics and product distribution for each case lead to a determination of the rate of vinylcarbene formation and, therefore, a direct determination of the relative carbene stabilities. The conclusion is that carbene 14 is more stable than 15. These results are then used as a basis for a discussion of the carbenes generated from ...
