and the internal alkyne in the carbene complex. All four of the possible phenol products of this reaction were independently synthesized, and the product distribution among the four isomers and the cyclopentenedione was investigated as a function of solvent, concentration, and the nature of the metal. The results of these experiments suggest that the phenol 13 arises from a vinylcarbene complexed intermediateand
