Synthesis and properties of 1,1′-bis[p-(N,N-dimethylaminophenyl)-butadiynyl]ferrocene: a methodology for proton-mediated reversible conformation control of two function sites
摘要:
An extended pi-electronic conjugation system of the 1,1'-bis[p-(N,N-dimethylaminophenyl)butadiynyl]ferrocene derivative 1 has been synthesized, with our integrated cross-coupling reaction between the corresponding TMS-protected acetylenes in one-pot. Quantitative H-1 NMR and UV-vis spectral studies of 1 have been performed, providing a methodology for molecular functions transformable by a proton-mediated reversible conformation control.
