Transmetalation (alt. spelling: transmetallation) is a type of
organometallic reaction that
involves the
transfer of
ligands from one
metal to another...
- or from
directed ortho-metalation.
Phenylsilanes and
phenylstannanes transmetalate with BBr3,
followed by
hydrolysis form
phenylboronic acid. Aryl halides...

organomagnesium compounds are
believed not the
active species. Instead, they
transmetalate to
organomanganese compounds,
which then
decompose to tert-butyl radicals...

first mechanism. In this mechanism, the
alkyl zinc
species would first transmetalate with the
nickel catalyst. Then the
nickel would abstract the halide...
- in
polar solvents copper transmetalate with the organostannane. The
resulting organocuprate reagent could then
transmetalate with the
palladium catalyst...
- with
sodium acetate and
hydrogen peroxide:
Organoboron compounds also
transmetalate easily,
especially to
organopalladium compounds. In the
Suzuki reaction...

Initiation from a metal(II)
species (either Ni or Pd)
involves two
monomers transmetalating onto the
metal center to form a
complex that can

- cycle. This is
usually achieved in situ in the
presence of
active transmetalating agents such as organo-magnesium, -zinc, -tin, or -boron reagents. Once...

These zirconium metallacycles can then be
transmetalated to
