Described herein is a distinctive approach to branched 1,3-dienes through oxidative coupling of two nucleophilic substrates, β-allenyl silanes, and hydrocarbons appending latent functionality by copper catalysis. Notably, C(sp3)-H dienylation proceeded in a regiospecific manner, even in the presence of competitive C-H bonds that are capable of occurring hydrogen atom transfer process, such as those located at benzylic and other tertiary sites, or adjacent to an oxygen atom. Control experiments support the intermediacy of functionalized alkyl radicals.

(Chemical Equation Presented) Various fluorodienes were prepared by treatment of the corresponding allenylmethylsilanes with Selectfluor. This is the first route to these compounds not based on the use of a fluorinated building block. The reaction allows

Successive treatment of 1-trimethylsilyl-2.3-butadienes with iodine and tetra-n-butylammonium fluoride in the same flask affords 2-iodo-1.3- butadienes in good yields and their palladium-catalyzed carbonylation and alkynylation allows introduction of este
