    • the case of ketones, the formation of dioxolanes is very slow even in DME, and therefore, DME can be employed as a solvent for the catalytic pinacol coupling to give 1,2-diol. On the other hand, the catalytic pinacol coupling reaction in THF at temperatures over 45 °C was accompanied by a ring opening reaction of THF
