A neutral thiolate–cycloheptatrienone adduct: the first direct evidence of base addition at two different, unsubstituted cycloheptatrienone carbon atoms
Abstract
2-(Dimethylthio)tropone tetrafluoroborate gives a ca. 1:1 equilibrium mixture of two neutral adducts after methanethiolate attack at C(3) and C(7), which slowly change into the adduct of methanethiolate attack on 2(methylthio)tropone.
