摘要
One sodium counterion in 1 can be selectively exchanged for PPh 4+, since the Na ions are distinguishable: complexation of one Na+ ion by two [(Cp*TiF3)2F]− fragments occurs through a “fluoride surface”. The anion in 1 thus belongs to a new class of host–guest complexes, since in molecular recognition studies so far the receptor surfaces of host molecules were almost exclusively formed from O, S, N, and/or P atoms. Cp* = η5‐C5Me5. (Figure Presented.) Copyright © 1992 by VCH Verlagsgesellschaft mbH, Germany
