The azomethine ylide generated from the reaction of sarconsine and formaldehyde adds to Gd@C82to give the mono- through octo-adducts, while the direct interaction of sarcosine with Gd@C82yields only the mono-adduct, which is characterized by HPLC, MALDI-TOF MS, UV-Vis-NIR and FT-IR. The reaction mechanism for this reaction is proposed to be a 1,3-dipolar addition. © 2004 Elsevier Ltd. All rights reserved.
