A transition metal-free C−N arylation of easily accessible tertiary anilines enabled by bifunctional arynes is described. The reaction proceeds via a tandem nucleophilic attack of anilines to arynes, followed by a Smiles-Truce rearrangement to furnish synthetically valuable and densely substituted biaryls. This protocol was further utilized for heterocyclic scaffolds, providing access to medium size

A photosensitive composition becoming sticky upon exposure to light which comprises (a) a salt of a diazonium compound represented by the formula
wherein R, and R2 are independently -H, -CH3, -OCH3 or
but R1 and R2 cannot be
at the same time; and R3 and R4 are independently a straight-chain lower alkyl group, and (b) a salt of an aromatic diazonium compound having no -OH group directly bonding to a benzene ring, has an improved sensitivity because it contains the salt of the compound represented by the above formula. By using said photosensitive composition, there is provided a process for forming a pattern of powder coated layer excellent in light sensitivity.
