Assay yields for desired product and remaining starting materials were determined by measuring its concentrations from a 50-70 mg aliquot of the reaction using standard HPLC techniques. Comparison of reaction rates under different light sources (Table S5). This type of reductive radical addition reaction, better known as the Giese reaction, was historically carried out most by using tributyltin hydride as the radical mediator . 2018-11-14 · Two named reactions of fundamental importance and paramount utility in organic synthesis have been reinvestigated, the Barton decarboxylation and Giese radical conjugate addition.

In particular, trapping of free-radicals with electron-deficient alkenes to form carbon-carbon bonds is called the Giese reaction. The newly formed α-carbon radicals can be reacted further with the second electrophiles in tandem fashion. The application of this reaction in intramolecular cyclization is common in natural product synthesis. Hydrogen abstraction by primarily formed radicals can be competitive with other reaction types such as addition to an unsaturated group to form a C C bond, which is known as the Giese reaction.

Tin-free Giese reactions, employing primary, secondary, and tertiary alkyl iodides as radical precursors, ethyl acrylate as a radical trap, and sodium cyanoborohydride as a radical mediator, were examined in a continuous flow system.

screened. The reaction of 1a with ethyl acrylate was found to give the desired Giese reaction product 3a together with two main byproducts, octane (2a) and the 1:2 addition adduct 4a. As shown in Scheme€2, higher reaction temperatures tended to result in the formation of increased amounts of octane (2a). Electronic Supplementary Information.
