• CMPO
• tripodal ligands
• actinides
• lanthanides
• nuclear waste
• selective alkylation

Novel tripodal CMPO ligands having either aryl groups at the N-atom or alkyl groups at the CMPO methylene bridge were prepared in good yields. In the latter case one alkyl group per CMPO Moiety was selectively introduced. Extraction studies with Am(3+) and Eu(3+) show that there is an influence of the electronic character of the aryl groups on the extraction. Alkylation of the CMPO methylene group gives rise to a considerable decrease of the D-values (about 100-1000 times), dependent on the bulkiness of the alkyl substituent.
