ABSTRACT
This mechanistic study demonstrates that an unusual η1 -coordinated alkyne complex is critical for the 1-pentyne 1,1-diboration reaction. The comparative studies suggest the "pull-push" antagonistic effect arising from Lewis acidity and steric congestion as the reason for the existence of η1 -coordinated alkyne complexes. Analogous η1 -coordinated alkene complexes are also predicted and seem to be promising for their application to the important olefin polymerization reaction.
