Efficiently Converting Thioether Waste to Organic Semiconductors by Carbon‐Sulfur Bond Activation

It is a sustainable development goal for human society to convert organic waste to valuable materials. Herein, 2‐(methylthio)‐bezothiazole (MTBT), an important organic waste in urban runoff, was catalytically converted to a series of organic semiconductors through carbon‐sulfur bond activation. The efficient conversion of various substrates with different aromatic moieties and reacting functional groups (tin and boron) proved the generality of this novel diarylation Liebeskind‐Srogl methodology. Moreover, the organic semiconductors showed excellent performances in field effect transistors and cell imaging. This contribution presents an excellent example of converting organic waste to valuable materials and may open a new avenue to utilize widely available aromatic thioethers.
