Reaction of Phosphorus Trihalides with Methyl Triflate. Molecular and Supramolecular Structure of Methyltrichloro- and Methyltribromophosphonium Triflates

摘要

Prolonged (similar to 4 years) keeping of mixtures of phosphorus trichloride or tribromide with methyl triflate in dark at 20-25 degrees C has led to the formation of crystalline methyltrichloro- and methyltribromophosphonium triflates with a content of 10-11% in the reaction mixture and yield of 5-6%. Structure of the triflates has been elucidated by means of X-ray diffraction analysis.
