Rate Constants for the Addition of 2‐Hydroxy‐2‐propyl Radicals to Alkenes in Solution studied by laser flash photolysis

Absolute rate constants for the addition of the highly nucleophilic 2‐hydroxy‐2‐propyl radical to eight fast‐reacting 1‐ and 1,1‐disubstituted alkenes in MeOH at room temperature have been determined by laser flash photolysis. Also the absorption spectra of the 2‐hydroxy‐2‐propyl and the benzylic and alkyl‐type adduct radicals are presented. The rate constants were obtained using various methods for the analysis of the kinetic traces and support earlier findings.
