Steps:

11 EXAMPLE 11

EXAMPLE 11 Dimethyl 2-(p-chlorophenyl)succinate was afforded in a yield of 59% in a similar manner as in Example 6, except that 1 mmol of p-chlorostyrene was used instead of styrene, and triphenylphosphine sulfide was employed in an amount of 0.2 mmol. ¹H-NMR (CDCl₃) δ: 2.66 (1H, dd, J=5.77, 16.76), 3.18 (1H, dd, J=9.62, 16.76), 3.17 (3H, s), 3.68 (3H, s), 4.07 (1H, dd, J=5.77, 9.62), 7.20-7.32 (4H, m) ¹³C-NMR (CDCl₃) δ: 37.38, 46.40, 51.89, 52.43, 128.98, 129.08, 133.57, 136.03, 171.61, 172.95 IR (cm^-1): 1740, 1490, 1440, 1160, 1100
