homocoupled
Homocoupled refers to a product or process in which two identical reacting partners join to form a single bond between two identical fragments, producing a homodimer or symmetrical product. In organic synthesis, homocoupling is a subset of coupling reactions, distinguished from cross-coupling where two different partners are joined. It can occur under catalytic conditions with metals such as nickel, palladium, or copper, and under oxidative, reductive, or radical pathways.
Common examples include the homocoupling of terminal alkynes to give diynes (the Glaser coupling) using copper
In radical and photoredox chemistry, two identical radical species may couple to form a dimer, providing another
