Acid-Catalyzed Activation of Peroxyketals: Tunable Radical Initiation at Ambient Temperature and below
Schweitzer-Chaput, Bertrand,Boess, Esther,Klussmann, Martin
, p. 4944 - 4947 (2016)
This study details how peroxyketals, commercially available thermal initiators, and structurally related peroxides are activated in the presence of an acid catalyst to generate radicals at room temperature and below. This simple combination of two substrates was shown to efficiently initiate a variety of radical processes. This phenomenon is rationalized by the acid-catalyzed in situ formation of highly unstable alkenyl peroxides which readily decompose into initiating radical species.

A protocol for performing atom transfer radical addition of activated alkyl chlorides to alkenes is described. The reaction is promoted by blue light in the presence of an organic photocatalyst (3DPA2FBN), serving to generate free radicals, and a copper c

The present invention refers to a process making use of a radical initiator system comprising peroxy compounds, in particular peroxyketals, in the presence of an acid catalyst to initiate radical processes at low temperature, such as room temperature and below.
