Regiospecific synthesis of bicyclo- and heterobicyclo-gem-difluorocyclobutenes using functionalized fluoroallenes and a novel Mo-catalyzed intramolecular [2 + 2] cycloaddition reaction.

Qilong Shen1, Gerald B Hammond.   

Abstract

The first synthesis of functionalized gem-difluoroallenes 4 served as platform for an unprecedented molybdenum-catalyzed intramolecular allene-alkyne [2 + 2]-cycloaddition that produced 6, a hitherto unknown class of bicyclo- and heterobicyclo-CF2-containing cyclobutenes.
