Methyl nitrite → 1,1-Dimethoxy-2-nitrosocyclopentane

Participants

Reaction Steps

1,1-Dimethoxy-2-nitrosocyclopentane dimer was prepared as in Example 1 by reacting 1-methoxycyclopentene (15.9 g., 0.162 mole) with an excess of methylnitrite (29.7 g., 0.48 mole) using 0.5 mole percent of 20% oleum as catalyst. The product (20.5 g.) was mostly the desired dimer with a small amount of 1,1-dimethoxy-2-oximinocyclopentane. An additional 5 grams of product were recovered by flash evaporation of the wash liquors. The structure was confirmed by IR and nmr.
