Saturated and unsaturated hydrocarbons

Further developments of radical deoxygenation methodology have included approaches to dideoxygenations, as well as dehalogenation and deaminati~n,'-~ whilst an electroreductive deoxygenation of a-methylsulfonyloxyesters via a catalytic selenation-deselenation sequence has also been rep~r ted .~ Radical decarboxylation procedures allow stereoselective alkylations with activated olefins of tartaric acid derived radicals, with retention of configuration (Scheme 1 )."
