Abstract: 2, 3-Bi (bromomethyl)quinoxaline reacts with disodium tetra rbony]ferrate at ambient temperature to give 2-bromo ethyl, 3- σ-methylenequinoxaline sodium tetracarbonylferrate (I) and 2, 3-bis(σ-methylene)qunoxalinetetracaronyliron(II) whereas with disodium cyclopentadnylmonocarbonylcobalt, it gives only 2, 3-bis(σ-methylene) quinoxalinecydopentadienylmonocarbonyl-cobalt(III). The complex I undergoes conversion into II in refluxing cyclohexane. The treatment of 2, 3-bis (bromo-methyl)quinoxaline with sodium tetracarbonylcobaltate yields 2, 3-bis(σ-methylene)quinoxalineoctacarbonyldi-cobalt(IV) .
