Collision-Activated Dissociation Spectra for the Characterization of the Diels-Alder Adducts between C_<60> and Troponoids

概要

• 論文の詳細を見る

• Diels-Alder adducts of C_<60> easily cycloreverted to the starting materials by heating. This property makes it difficult to determine the molecular weight of adducts by means of mass spectrometry. We employed collision-activated dissociation spectra to characterize the Diels-Alder adducts of C_<60> with troponoids, cycloheptatriene, and 2-cycloalkenones and their acetals since the molecular peak of C_<60> as well as peaks derived from C_<60> were intense. This technique is useful for the determination of the molecular weight of thermally labile compounds.
