Al3+, in which the induction of Fe3+ was highly prone to the degradation of α-asarone. Thus, an iron (III)-mediated forced degradation study of α-asarone was carried out. One oxidative and four dimeric products were formed after the degradation of α-asarone. The complete mass fragmentation patterns for α-asarone and its degradationproducts (DPs) were established by UPLC-MS/MS in the positive ionization
A methodology for the dimerization of substituted styrenes is reported using a PhP(O)HOR/Mn(II)/Co(II)O2 catalyst, in which the alkyl phenylphosphinate compound acted as a catalyst rather than a substrate as is generally observed. Mechanistic studies suggested the reaction most likely proceeded via addition–elimination.
