Heating 1-Z-3,4-dimethylphospholes with potassium tert-butoxide in THF at ca. 150-160 °C affords the corresponding potassium 2-Z-3,4-dimethylphospholides (Z = 1-methyl-2-pyrrolyl and 2-(diphenylphosphino)phenyl) via a [1,5]-sigmatropic shift of Z. The first anion can be used to prepare the corresponding bis(pyrrolyl)-1,1′-diphosphaferrocene, and the second anion is able to chelate palladium(II) between its phospholide and PPh2 functionalities.
