Title: Is Water Really Deleterious For Organometallics Anchoring Into Zeolites?
Author: De Oliveira E.C.
Pastore H.O.
Abstract: Anchoring of [(η5-C5H5) Rh(η4-C8H12)] into cavities of Na 56Y and H56Y zeolites was studied. In contrast to expectation, the zeolite degree of hydration is not a key factor in the organometallic structural integrity. The thermal behavior of the occlusion reaction is the same when the zeolites are completely or partially dehydrated, showing that total absence of water is not a necessary condition to prepare an organometallic/zeolite system. For the zeolite Na56Y the product is the organometallic fragment [(n5-C5H5)Rh] which anchors to the oxygen atoms of the framework, while for the H56Y zeolite the product is a cationic organometallic species.
