Abstract

Abstract The title complex has been synthesized by refluxing a toluene solution of Co 2 (CO) 8 and the diyne [(HC CCMe 2) 2 NMe]. It has been characterized by IR and NMR spectroscopy and its structure determined by an X-ray diffraction study. The complex is one of the few examples of a crystallographically characterized cobaltacyclopentadiene derivative. It can be considered to be an intermediate in the cyclization reaction of ...
