Chlorination using NCS has been found to be applicable for use with a wide range of aromatic starting materials or substrates, as is shown in Table 2. All the substrates treated with 1 equivalent of NCS and 5 mole % of ZrCU afforded the corresponding chlorinated compounds. The reaction at room temperature afforded a high yield of chlorinated product with high regioselectivity. In some cases, a small amount of regioisomers (Entry 3) or dichlorinated products (Entries 4 and 5) were observed.Table 2 ZrCIj Catalyzed Chlorination of Aromatic Compounds by NCS2-CI : 4-CI (13: 87)b EPO
