Electron-deficient thiophene dioxides have been found to react rapidly with a bicyclo[6.1.0]non-4-yne derivative to afford benzocyclooctenes in excellent yields. Thiophene dioxides bearing a clickable functional group served as efficient bisreactive platform molecules that enabled sequential molecular conjugation in a simple operation.

Sulfurtetrafluoridefluorinations of bicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxylic acid dianhydrides provided an access to many polyfluorinated, polycyclic alkenes of a new structure. Factors responsible for the successful outcome include electronic character of substituents and reaction conditions. The thorough spectral analysis of isolated products led to the discovery of “through space” couplings
The present invention relates to a new method for the manufacture of substituted biphenyl amines, new intermediate products and their manufacture, as well as a method for the manufacture of fungicidally active carboxamides.
