Direct C-H alkylation is one of the most important C-C bond formation events and is crucial to the efficient assembly of functionalized carbon skeletons in synthetic chemistry. We report herein a photoinduced palladium-catalyzed strategy for the direct alkylation of allylic C-H bonds. The success of this transformation relies on the use of 2-bromo-1,3-dimethylbenzene as a hydrogen atom transfer (HAT) mediator, in combination with a carbon nucleophile, facilitated by a palladium catalyst activated by blue light. Unlike classical Pd(II/0) pathways, this approach leverages the versatile reactivity of Pd(0/I/II) species through visible-light excitation, establishing a robust foundation for the feasibility of this synthetic methodology.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Aldehydes and Ketones to Alkenes: Wittig Reaction Mechanism
The reaction begins with the nucleophilic addition between a phosphorus ylide and the carbonyl compound. Due to its carbanionic character, phosphorus ylide acts as a strong nucleophile and attacks the electrophilic carbonyl group. This generates a charge-separated dipolar intermediate called betaine. The negatively charged oxygen atom and...

Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.
