Selective synthesis of seven-membered cyclic thione analogues of acid anhydrides and other related derivatives via a benzannelated nickelacycle
Abstract
The ready available benzonickelacyclopentene complex (Me3P)2[graphic omitted]6H4)(1) has been used to prepare a series of seven-membered ring thione analogues of acid anhydrides and other related derivatives through regioselective sequential insertion reactions of selected unsaturated molecules (CS2, COS, SCNPh, CO, CNBut) into the Ni–C bonds.
