3-Chlorocyclopent-1-ene → 3-(3-[(1,1-Dimethylethyl)dimethylsiloxy]pent-1-yl)cyclopentene [3-(2-cyclopenten-1-yl)-1-ethylpropoxy](1,1-dimethylethyl) dimethylsilane

Participants

Reaction Steps

The procedure followed is the same as that described in Example 20 substituting (5-chloro-3-pentyloxy)(2,2-dimethylethyl)dimethylsilane {3-chloro-1-ethylpropoxy)(1,1-dimethylethyl) dimethylsilane,} (78 g, 0.33 moles) diluted in tetrahydrofuran (100 ml), granular magnesium (24 g, 1.00 moles) in tetrahydrofuran (100 ml), 0.1 M solution of Li2CuCl4 (1.0 mmole), 3-chlorocyclopentene (33 g, 0.33 moles) diluted in tetrahydrofuran (50 ml). The crude product is distilled under reduced pressure leaving a clear yellow oil (21 g, 0.078 moles), BP 69° C./ 0.1 mm.
