摘要

The electronic structure of the transition state for the cyclopropylidene to allene conversion has been probed. The methodology involved the relative rates of ring opening va trapping by MeOH for a series of variously substituted 2, 3-diarylcyclopropylidenes. With the assumption that the rate of trapping was unaffected by Substituents, a Hammett correlation was construded. The negative value (-0.72) for p indicated that the carbenic center attra& ...
