Abstract (en)

[origin: WO2005077863A1] The invention relates to a method for establishing carbon-carbon bonds by reacting electropohilic substrates that have a solvolysis rate kEtOH (25°C) > 10<-6> s<-1> and pi compounds. The method is characterized by generating the intermediary carbocations in neutral to alkaline aqueous or alcoholic solvents or solvent mixtures without using a Lewis or Brönsted acid.
