First X-Ray Crystal Structure and Internal Reference Diffusion-Ordered NMR Spectroscopy Study of the Prototypical Posner Reagent, MeCu(SPh)Li(THF)3

Grow slow: The usual direct treatment of MeLi and CuSPh did not yield X‐ray quality crystals of MeCu(SPh)Li. An indirect method starting from Me2CuLi⋅LiSPh and chalcone afforded the desired crystals by the slow reaction of the intermediate π‐complex (see scheme). This strategy produced the first X‐r...

Summary:Grow slow: The usual direct treatment of MeLi and CuSPh did not yield X‐ray quality crystals of MeCu(SPh)Li. An indirect method starting from Me2CuLi⋅LiSPh and chalcone afforded the desired crystals by the slow reaction of the intermediate π‐complex (see scheme). This strategy produced the first X‐ray crystal structure of a Posner cuprate. A complementary NMR study showed that the contact ion pair was also the main species in solution.
