2-(4-Methoxyphenyl)-1,3-dithiolane → 1-Methoxy-4-(trichloromethyl)benzene

Participants

Reaction Steps

5.8 gm (0.0274 moles) of the dithiolane of Example 4 was reacted following the procedure of Example 6 to give 5.01 gm of a 3.8:1 mixture of 3-methoxybenzaldichloride and 3-methoxybenzotrichloride (b.p. 83°-84° C. at 0.3 mm/Hg). NMR and GC/MS Analysis for Product: 1H--NMR (CDCl3), δ3.63 (S, 3H, OCH3), 6.7 (d, J=13.5 Hz, 2H), 7.65 (d, J=13.5 Hz, 2H); GCMS (70 ev), M/e (% rel. int.) 228 (M+ +4, 3.3), 226 (M+ +2, 9.2), 224 (M+, 9), 193 (17), 191 (93), 189 (100).
