The transposed Paternò−Büchi reaction involves a
ππ* excited state of
alkene
In organic chemistry, an alkene is a hydrocarbon containing a carbon–carbon double bond.
Alkene is often used as synonym of olefin, that is, any hydrocarbon containing one or more double bonds.H. Stephen Stoker (2015): General, Organic, an ...
reacting with a
ground state
The ground state of a quantum-mechanical system is its stationary state of lowest energy; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater than the ground state. ...
carbonyl
In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O. It is common to several classes of organic compounds, as part of many larger functional groups. A compound containing a ...
functionality. This is reversal of the traditional
Paternò−Büchi reaction where an excited carbonyl group reacts with a ground state alkene. This strategy was first reported by
Sivaguru and co-workers with reaction of
enamides.
