Host-Guest Behavior of a Heavy-Atom Heterocycle Re-4(CO)(16)(mu-SbPh2)(2)(mu-H)(2) Obtained from a Palladium-Assisted Ring Opening Dimerization of Re-2(CO)(8)(mu-SbPh2)(mu-H)
The heavy-atom heterocycle Pd[Re-2(CO)(8)(mu-SbPh2)(mu-H)](2) (5) has been synthesized by the palladium-catalyzed ring-opening cyclodimerization of the three-membered heterocycle Re-2(CO)(8)(mu-SbPh2)(mu-H) (3). The Pd atom occupies the center of the ring. The Pd atom in 5 can be removed reversibly to yield the palladium-free heterocycle [Re-2(CO)(8)((mu-SbPh2)(mu-H)](2) (6).
