Abstract :
1-Vinylpyrrole-2-carbaldehydes react with phosphorus pentachloride (benzene, 10–15 °C) to afford E-2-(2-dichloromethylpyrrol-1-yl)vinylphosphonium hexachlorophosphates in up to 85% yield, which after treatment with SO2 (benzene, rt) are converted into E-2-(2-dichloromethylpyrrol-1-yl)vinylphosphonyl dichlorides in 50–75% yields.
