WebThe diagram below illustrates this concept, showing that electrophilic carbons attached to three hydrogen atoms results in faster nucleophilic substitution reactions, in comparison to primary and secondary haloalkanes, which result in nucleophilic substitution reactions that occur at slower or much slower rates, respectively. The rate at which organostannanes transmetalate with palladium catalysts is shown below. Sp -hybridized carbon groups attached to tin are the most commonly used coupling partners, and sp -hybridized carbons require harsher conditions and terminal alkynes may be coupled via a C-H bond through the Sonogashira … See more The Stille reaction is a chemical reaction widely used in organic synthesis. The reaction involves the coupling of two organic groups, one of which is carried as an organotin compound (also known as organostannanes). … See more The mechanism of the Stille reaction has been extensively studied. The catalytic cycle involves an oxidative addition of a halide or … See more Electrophile Vinyl halides are common coupling partners in the Stille reaction, and reactions of this type are found in numerous natural product total syntheses. Normally, vinyl iodides and bromides are used.
