Methylenecyclopropanes (MCPs) are easily accessible yet highly strained and reactive building blocks. MCP can be readily opened under transition metal or Lewis acid catalyzed conditions. We have hypothesized that a highly polar and Lewis acidic reaction medium could facilitate the ring opening of MCPs with simple nucleophiles. We have recently shown that liquid sulfur dioxide perfectly fulfils the aforementioned solvent requirements. Additionally, it dissolves well inorganic salts. Here we report ring opening of MCPs in liquid SO2 with I and II group metal halides.
