Alkynes behave quite like alkenes when it comes to carbene addition. For example, a carbene can add to an alkyne to yield a cyclopropene, as shown here. Alkynes behave differently from alkenes, however, when treated with a peroxyacid. Whereas an alkene would be converted into an epoxide by the addition of an oxygen atom, this addition product is not observed for alkynes under normal conditions. Suggest why. Hint: Pay special attention to the lone pairs. CH,N2 C=C hv RCO3H -C=C-
