Palladium-Catalyzed Secondary C(sp3)?H Arylation of 2-Alkylpyridines

A pyridyl group-assisted palladium-catalyzed secondary C(sp3)?H arylation protocol was developed. A substituent at the 3-position of the pyridyl group is proved to be important for promoting C?H arylation and controlling the regioselectivity. Aryl iodides can be used as coupling partners. The reaction proceeded in good to excellent yields with good functional group tolerance, even on the gram-scale. The preliminary asymmetric reaction was investigated using an L-proline derivative as a chiral ligand. (Figure presented.).

TRIARYLAMINE COMPOUNDS, COMPOSITIONS AND DEVICES

The invention relates to a compound of Formula (I): wherein: each of R1, R2, R3, R4, R5, R6 and R7 which may be the same or different on each triarylamine unit of Formula (1) and the same or different from one triarylamine unit of Formula (1) to another is independently hydrogen or an optionally substituted substituent; n is from 5 to 20; and a and b are each independently 0, 1, 2, 3 or 4. Also claimed are compositions comprising a compound of Formula (1) and a synthetic organic polymer resin, a process for preparing a compound of Formula (1), an organic semiconducting layer prepared from the composition, and electronic devices comprising the organic semiconducting layer.
