conditions, trapped by a variety of nucleophilic reagents, and used to access a number of novel substituted indoles. Nucleophilicaddition reactions to indolynes proceed with varying degrees of regioselectivity; distortion energies control regioselectivity and provide a simple model to predict the regioselectivity in the nucleophilicadditions to indolynes and other unsymmetrical arynes. This model

A mild method to access a variety of substitutedindole derivatives has been developed. The strategy relies on the generation of highly reactive indolyne intermediates, which function as electrophilicindole surrogates.

The present invention relates to the use of dibenzofurans and dibenzothiophenes which have at least one nitrogen-bonded five-membered heterocyclic ring as a substituent as host, blocker and/or charge transport material in organic electronics. The present invention further relates to dibenzofurans and dibenzothiophenes which comprise at least one nitrogen-bonded five-membered heterocyclic ring and at least one carbazolyl radical as substituents, to a process for preparation thereof, and to the use of these compounds in organic electronics.

An annulation reaction proceeding by the intermolecular addition of an arylpalladium(II) halide across a strained alkene, followed by an intramolecular C-H functionalization of a pendant heterocycle is described. A variety of polycyclic heterocycles have been prepared from readily accessible haloaryl heterocycles by annulation with a range of strained alkene partners.
