By the salt formation with particular nonaromatic dicarboxylic acids, rapid and selective photodimerization of 9-(N,N-dimethylaminomethyl)anthracene (1) was accomplished in the solid state. For instance, the salt with trans,trans-muconic acid or acetylenedicarboxylic acid was led quantitatively to the 9,10:4′,1′ photodimer usy-ht-2, the first example of the unsymmetrical [4+4] photodimerization of anthracene in the solid state. The reactions were rationalized by the relevant C...C distances between the reacting carbons.

An unprecedented aromatic substitution reaction of benzylic ammonium salts has been developed through palladium-catalyzed C-N bond cleavage. A range of primary and secondary amines participated in a palladium-catalyzed aromatic substitution reaction of benzylic ammonium salts, delivering sterically hindered aromatic amines in moderate to excellent yields with extremely high regioselectivity. Preliminary mechanistic studies permitted successful identification of Π-benzylpalladium complexes and Γ-vinyl allylic amines as key intermediates. This study paves the way for the use of benzylic ammonium salts in the aromatic substitution reactions.
