Abstract

The heavy-atom heterocycle Pd[Re2(CO)8(μ-SbPh2)(μ-H)]2 (5) has been synthesized by the palladium-catalyzed ring-opening cyclodimerization of the three-membered heterocycle Re2(CO)8(μ-SbPh2)(μ-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 [Re2(CO)8((μ-SbPh2)(μ-H)]2 (6).

摘要

通过钯催化的三元杂环Re2(CO)8(μ-SbPh2)(μ-H)(3)的开环环二聚反应合成了重原子杂环Pd[Re2(CO)8(μ-SbPh2)(μ-H)]2(5)。钯原子占据环的中心。5中的钯原子可以可逆地除去，生成无钯杂环[Re2(CO)8((μ-SbPh2)(μ-H)]2(6)。
