(hetero)arylhalides, including challenging aryl chlorides, with a variety of aromatic and aliphatic thiols. Aryl and alkenyl tosylates are also well tolerated, demonstrating, for the first time, to be competent electrophilic partners in Ni-catalyzed C−S bond formation. The chemoselective functionalization of the C−I bond in the presence of a C−Cl bond allows for designing site-selective tandem C−S/C−N
A catalytic system of regioselective synthesis of allyl sulfides via hydrothiolation of terminal arylallenes with arylthiols has been developed using nickel(0) complex Ni (PMe3)4 as a catalyst. In most cases the excellent to moderate yields were obtained under mild conditions. A catalytic mechanism was suggested and partially‐experimentally verified. To the best of our knowledge, this is the first
