Versatile deuterium exchange and isomerization of hydrocarbons via phase transfer catalysis
Abstract
The complete deuteriation of indene (1) at C(1) and C(3) and fluorene (2) at C(9), and the allylic isomerization of 1-methylindene (3) to 3-methylindene (6) are reported; phase transfer catalysis is shown to be an easy and efficient method for deuterium exchange and isomerization of acidic hydrocarbons.
