On the relative acidity of cycloheptatriene and toluene
Abstract
The proton of the cycloheptatrienyl moiety in 7-benzylsulphonyl-1,3,5-cycloheptatriene is found to be at least 300 times more acidic than those of the benzyl moiety in the same molecule towards potassium amide in liquid ammonia (at –40 °C).
