Arylation of potassium 2,4-pentanedionate via S(RN)1 on diazosulfides
Dell'Erba,Novi,Petrillo,Tavani,Bellandi
, p. 333 - 342 (2007/10/02)
Potassium 2,4-pentanedionate reacts with diazosulfides (E)-1 and (Z)-2 in DMSO to give 3-aryl-2,4-pentanediones 3 via an S(RN)1 process. Advantages and drawbacks of such new access to 3 are reported together with relevant mechanistic implications.
