Cross-linking dendrimers with allyl ether end-groups using the ring-closing metathesis reaction
Elmer, Stephanie L.,Zimmerman, Steven C.
, p. 7363 - 7366 (2004)
A third generation Frechet-type dendrimer containing 24 allyl ether end-groups was synthesized, cross-linked using the ring-closing metathesis (RCM) reaction, and the core was removed hydrolytically without significant fragmentation. The results are analo
