A Ni-catalyzed cross-coupling of aryl thioethers with alkyl Grignardreagents, accompanied by the cleavage of the C(aryl)–SMe bond, has been presented. This method is distinguished by its mild conditions and moderate functional group tolerance, such as hydroxyl, halogen, and heterocycles, which should provide a straightforward access to the modification of sulfur-containing molecules.

RhCl3-catalyzed peri-selective C−H/C−H oxidative homo-coupling of 1-substituted naphthalenes is developed to access chalcogen-embedded anthanthrenes. S-embedded anthanthrene (PTT) exhibits hole transport with a mobility of 1.1 cm2 V−1 s−1. The transformation of p-type to n-type semiconductors is realized via the S-atom oxidation of PTT, and the resulting PTT-O4 shows electron transport with a mobility
