title: Accelerating influence of the gem-difluoromethylene group in a ring-closing olefin metathesis reaction. A Thorpe-Ingold effect?
abstract: The gem-difluoromethylene (CF2) group significantly accelerates ring-closing metathesis of 1,8-nonadienes relative to the methylene (CH2) group demonstrating similar rate accelerations to that observed for the classic Thorpe-Ingold substituents, diester malonates and ketals.
