Diborylated ferrocene polymers

Figure 23 Charge transfer coordination polymers (33) obtained from diborylated ferrocenes with 4,4 -bipyridine (bipy) or 1,2-bis(4-pyridyl)ethane (pyetpy) bridges. (Adapted from ref. 55.)...

Similar polymers (34) (Fig. 24) of diborylated ferrocenes linked by pyrazine units were developed that had an unusual dark-green appearance indicative of charge-transfer interactions between the iron centers and the electron-poor pyrazine adduct bridges.56... 

Borylated ferrocenes have been exploited by Wagner as building blocks for the assembly of macrocycles and coordination polymers (Scheme 15). Treatment of the diborylated ferrocene l,L-fc(BMe2)2 with the bifunctional aromatic amines pyrazine and 4,4 -bipyridine, respectively, led to spontaneous and reversible formation of (89) and related ferrocenylborane polymers.The polymeric nature of...
