Resumen:
Aryl or alkyls halides (RX) that do not undergo SN2 nor SN1 reaction could be usually activated by electron transfer (ET) to participate in substitution reactions (SRN1 reaction). This mechanism is a chain process with radicals and radical anions as intermediates. As t-BuOK can form [RX]-. by ET in photostimulated SRN1 reactions,we speculated that the arylation or alkenylation could only be achieved with t-BuOK and light. In the present work, we present two different approaches: alkylation of arenes (benzene and heterocycles) and C-H alkenylation of haloarenes, by photoinduced ET without the addition of transition metals or ligands.
