Arylation of potassium 2,4-pentanedionate via SRN1 on diazosulfides
摘要:
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.
