Alkaline-earth-metal arenesulfonates as precursors to organic derivatives of Group 2 metals

Abstract

Treatment of the readily accessible alkaline-earth-metal arenesulfonates M(OSO₂R)₂(from MCO₃+ 2RSO₃H) with one of a range of Li, Na or K organic compounds in tetrahydrofuran (thf) afforded the corresponding alkaline-earth-metal organic compound in high yield, including the novel compounds LiM(OSO₂R)₂[CH(SiMe₃)₂](thf) and KM[CH(SiMe₃)₂]₃(thf)₃(M = Ca, Sr or Ba; R = C₆H₄Me-4, C₆H₂Me₃-2,4,6 or C₆H₄Bu^t-4.
