Abstract
![]()
The ortho-deprotonation
of halide-substituted
ferrocenes by treatment with lithium tetramethylpiperidide (LiTMP)
has been investigated. Iodo-, bromo-, and chloro-substituted ferrocenes
were easily deprotonated adjacent to the halide substituents. The
synthetic applicability of this reaction was, however, limited by
the fact that, depending on the temperature and the degree of halide
substitution, scrambling of both iodo and bromo substituents at the
ferrocene core took place. Iodoferrocenes could not be transformed
selectively into ortho-substituted iodoferrocenes
since, in the presence of LiTMP, the iodo substituents scrambled efficiently
even at −78 °C, and this process had occurred before electrophiles
had been added. Bromoferrocene and certain monobromo-substituted derivatives,
however, could be efficiently ortho-deprotonated
at low temperature and reacted with a number of electrophiles to afford
1,2- and 1,2,3-substituted ferrocene derivatives. For example, 2-bromo-1-iodoferrocene
was synthesized by ortho-deprotonation of bromoferrocene
and reaction with the electrophiles diiodoethane and diiodotetrafluoroethane,
respectively. In this and related cases the iodide scrambling process
and further product deprotonation due to the excess LiTMP could be
suppressed efficiently by running the reaction at low temperature
and in inverse mode. In contrast to the low-temperature process, at
room temperature bromo substituents in bromoferrocenes scrambled in
the presence of LiTMP. Chloro- and 1,2-dichloroferrocene could be ortho-deprotonated selectively, but in neither case was
scrambling of a chloro substituent observed. As a further application
of this ortho-deprotonation reaction, a route for
the synthesis of 1,3-disubstituted ferrocenes was developed. 1,3-Diiodoferrocene
was accessible from bromoferrocene in four steps. On a multigram scale
an overall yield of 41% was achieved. 1,3-Diiodoferrocene was further
transformed into symmetrically 1,3-disubstituted ferrocenes (1,3-R2Fc; R = CHO, COOEt, CN, CH=CH2).
