E‐Selective Hydrothiolation of Terminal Arylallenes with Arylthiols Catalyzed by Ni (PMe3)4.

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 example of regioselective addition of thiophenols to terminal arylallenes catalyzed by nickel(0) complex. It was noteworthy that this catalytic system was only applicable to thiophenol compounds with terminal arylallenes. [ABSTRACT FROM AUTHOR]
