Acetoxymercuration of a series of acylferrocenes has been found to produce appreciable amounts of 1,2- as well as 1,1′-mercurated products. The mercurated derivatives were readily converted into a variety of other unsymmetrical 1,2- and 1,1′-disubstituted ferrocenes. The 1,2-orientation of sub...

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 s...

The synthesis of 1,1′-bis(N-ter-butyl-N-hydroxyamino)ferrocene 1, is described, and the X-ray analysis showed eclipsed positions of the two ter-butylhydroxyamino groups; this structure can be explained by the interactions of the hydroxyl hydrogens with the nitrogen atoms of the other ter-butylh...

Treatment of bis-triorganotin sulfides (R3Sn)2S or diorganotin sulfides R2SnS with diferrocenylmercury gives triorganostannylferrocenes and diorganostannyldiferrocenes, respectively. Reaction of R2SnS with chloromercuriferrocene and 1,1′-bis(chloromercuri)ferrocene gives diorganochlorostannylfe...
