    • The use of Ni(0) catalyst which was prepared from Ni(II) and BuLi was not so effective. On the contrary Ni(II) catalyst gave the product with a reasonable yield. In this case, the formation of a radical species from benzylnickel intermediate may be a possible route. In fact, the addition of TEMPO interfered with the reaction. In the reaction of alkenyl sulfide with arylmethylzinc bromide (entry 4 in Table 3) addition of TEMPO (1 equiv) resulted in the low yield of 6a (14%).

    • Preparation of (E)-1-Phenyl-1,4-pentadiene (3a, To a solution of nickel(II) chloride (0.10 mmol) and tris(2-furyl)phosphine (0.20 mmol) in THF (0.5 mL) under argon, n-BuLi (0.2 mmol, 1.6 M in hexane) was added and stirred for 15 min at 25°C. To the mixture, after a solution of (E)-1-phenylthio-2-phenylethene (1a) in THF (1.0 mL) was added, allylzinc chloride (2a; 2.0 mmol, 0.7 M in THF) was added dropwise. The resulting mixture was stirred for 4 h at 60°C. After aqueous workup, purification by silica gel column chromatography gave (E)-1-phenyl-1,4-pentadiene (3a) in 99% yield. 1H NMR (300 MHz, CDCl3, δ, 7.17-7.37 (m, 5 H, 6.42 (d, J, 15.9 Hz, 1 H, 6.23 (dt, J, 6.3, 15.9 Hz, 1 H, 5.90 (ddt, J, 6.3, 10.5, 15.9 Hz, 1 H, 5.05-5.16 (m, 2 H, 2.97 ddt, J, 1.5, 6.3, 6.3 Hz, 2 H
