✦ Synopsis

The remarkable stability of a-ferrocenylcarbenium ions is evident from solvolysis experiments 1 as well as generation from carbinol precursors in acid media and direct spectroscopic observation.

2 The latter has also permitted determination of pKR-values for the carbinol-carbenium ion equilibria. 3 In some cases salts containing the carbenium ion have been isolated. 4 Despite the great current interest in this field, however, the synthetic usefulness and importance of such salts do not seem to have been recognized.

This communication describes a simple route for the preparation of some different a-ferrocenylcarbenium tetrafluoroborates (I) and their ready conversion

Synthetic antigens are simple compounds, the chemistry of which is not only known but also to a large extent controlled at will. Another milestone of modern immunochemistry is the recent availability of synthetic water-soluble adjuvants. It is the belief of the authors that an approach combining the
