Carbolithiation of diphenylacetylene can be exploited to generate (E)-1-lithio-1,2-diphenylalkyl-1-enes which can be reacted in situ with triisopropylborate to stereoselectively provide (E)-1,2-diphenyl-1-alkylene boronic acids. These tetrasubstituted vinylboronic acids served as versatile intermediates for the generation of tetrasubstituted olefins with retention of

The conformational equilibrium of a pH-dependent switch based on an intramolecularly H-bonded diphenylacetylene can be predictably biased by using electron-donating or -withdrawing groups. Furthermore, protonation of the electron-donating dimethylamino group converts it into an electron-withdrawing dimethylammonium cation with a concomitant

[reaction: see text] A variety of substituted beta- and gamma-carbolines have been prepared in good to excellent yields by the annulation of internal acetylenes by the tert-butylimines of N-substituted 3-iodoindole-2-carboxaldehydes and 2-haloindole-3-carboxaldehydes, respectively, in the presence of a palladium catalyst.
