Front Cover Picture: Electrochemical ipso‐Thiocyanation of Arylboron Compounds (Adv. Synth. Catal. 15/2019)

The front cover picture, designed by Marco Dyga from the group of Lukas J. Gooßen, illustrates an electrochemically enabled synthesis of aryl thiocyanates. The electrolysis of inexpensive, non-toxic thiocyanate salt yields the reactive pseudohalogen thiocyanogen, (SCN)2. Its reaction with arylboron compounds, e.g., aryl trifluoroborates, in a metal-free, electrophilic ipso-substitution, yields the corresponding thiocyanates, which are widely used as intermediates in medicinal chemistry. Details of this work can be found in the communication on pages 3548–3553 (M. Dyga, D. Hayrapetyan, R. K. Rit, L. J. Gooßen, Adv. Synth. Catal. 2019, 361, 3548–3553; DOI: 10.1002/adsc.201900156).
