An oxidative rearrangement of tertiaryalcohols mediated by m-CPBA is described that generates tetrasubstituted alkenes with a carboxylic acid substituent. The mechanism of the reaction is proposed to proceed through epoxidation of the alkyne to form an oxirene that undergoes a 1,2-aryl shift.

The first catalytic addition of terminal alkynes to simplecyclicketones in water catalyzed by silver was developed. Cyclicketones were reacted with terminal alkynes efficiently in water to give the corresponding propargyl alcohols.
