3,2,1 and stop! An innovative, straightforward and clean route for the flash synthesis of metallacarboranes

Abstract

[Co(C2B9H11)2]-, analogs to metallocene, can be readily synthesised in high yield by a fast and clean solvent-free reaction of [HNMe3][C2B9H12] with CoCl2·xH2O. This innovative approach, applied to both ortho and meta isomers, yields the desired structures by simply heating the solid compounds to high temperature for a very short time.
