Dimerization of Boryl- and Amino-Substituted Acetylenes by B2C2 Four-Membered Ring Formation

Abstract

Boryl- and amino-substituted acetylenes bearing diphenylboryl- or 9-borabicyclononyl-groups were synthesized. X-ray diffraction analysis revealed the dimerized structures of these acetylenes through a formation of B2C2 four-membered ring. Spectroscopic studies as well as DFT calculation indicated that these dimers can dissociate to monomeric acetylene, in which the equilibrium constant for the dissociation depends on the structure of boryl substituents.
