Methods of synthesizing compounds comprising fluorinated aryl groups are disclosed, wherein said methods utilize hydrogen bond directed photocatalytic hydrodefluorination.
1,4-Disubstituted semicarbazides I, dithiocarbazates II, III and diesters of N-(2,6-dialkylphenylamino)imidodithiocarbonic acid IV, V were prepared from 2,6-dialkylphenylhydrazines. The products were tested for pesticide activity.

The synthesis of N,N-dimethyl-N-[(pyrro-1-yl)methyl]anilinium chloride (14) and of the corresponding p-toluidinium salt 15 is described. These salts, when dissolved in polar solvents, are shown to be in equilibrium with 1-(chloromethyl)pyrrole (17) and thereby potentially with the 5-azoniafulvene ion (2). Consequently, they react under very mild conditions (MeCN, 60°) with enamines to give pyrrolizine
