Some aspects of the mercuriation of ferrocene

Add time:08/01/2019    Source:sciencedirect.com

The kinetics of mercuriation of ferrocene with Hg(OAC)2 have been reinvestigated and the data interpreted in terms of rapid complex formation followed by rate determining conversion of the complex to products. The nature of analogous complexes with HgCl2 was investigated by an NMR method which suggested the formation of a 1:1 iron-bound mercury species. Product analyses of the mercuriation reaction revealed evidence for homoannular disubstitution. The homoannular derivative is subsequently converted to the 1,1'-disubstituted product. Improved syntheses ot the acetatomercuri ferrocenes is also reported.
