Abstract

Abstract : Highly efficient rhodium(iii ) catalysis was developed for obtaining structurally divergent pyrazolone analogues from pyrazolones and non-activated free allyl alcohols. Abstract : Highly efficient rhodium(iii ) catalysis was developed for obtaining structurally divergent pyrazolone analogues from pyrazolones and non-activated free allyl alcohols. Notably, this new C–H activation reaction generated unexpected pyrazolo[1, 2- α ]cinnoline derivatives besides γ-ketone substituted edaravone derivatives, and the selectivity of this coupling reaction could be controlled by changing the conditions.
