Radical nucleophilic substitution of 2-(4-halophenyl)-2-methyl-1-chloropropane with enolate ions of ketones

Autor: Mariana H. Gallego, Karina Fernanda Crespo Andrada, Adriana B. Pierini

Publikováno v: The Journal of organic chemistry. 72(8)

The photoinitiated reaction of 2-(4-halophenyl)-2-methyl-1-chloropropane 2a,b (halogen=Br, I, respectively) with the anions of pinacolone (3a) and acetophenone (3b) either in DMSO or in liquid ammonia are reported. In DMSO, the main reaction is the S
