Abstract

In the title compound 1 the electron-deficient alkyne bond shows a pronounced trans distortion in response to an adjacent electron rich nitro O atom, suggesting that the more favourable reaction coordinate for addition of nucleophiles to activated alkynes involves trans rather than cis addition.
