Figure 4.
Job plot showing the relative integrations versus the intended mole fraction of TMEDA for a mixture of 0.20 M of enolate 2 and 1.0 M total diamine concentration in TMEDA/(S,S)-TMCDA mixtures in toluene at −80 °C. The shift in the maximum to χTMEDA > 0.50 reflects the stronger binding of (S,S)-TMCDA.
