Abstract
The first observation of the stereospecificity in the benzyne-olefin [ 2 + 2] cycloaddition is The key points reside in (1) the efficient met hod for generating benzyne species by the halogen-lithium exchange rea ction of ortho-halo aryl triflates, and (2) the choice of ketene silyl acetal as the partner olefin.
