Abstract
Zerovalent group
6 dinitrogen phosphine complexes react with 3,3-diphenylcyclopropene
to give vinylcarbyne hydride complexes that have been characterized
crystallographically. Computational studies indicate that the observed
products resulted from the α-migration and rearrangement of
an initially formed vinylcarbene
