Abstract
Ionized N-aryl-3,4-diphenylisoxazol-5(2H)-one isomers react unimolecularly in the gas-phase mainly via carbon dioxide elimination. The observed ring contraction closely resembles the reported behaviour of the corresponding neutral compounds in solution. The reacting species were produced by electron impact (EI) and field ionization (FI) and analyzed by MS/MS through the determination of specific metastable ions (MI) decompositions.File in questo prodotto:
