A Novel High-yield Route to Organic Derivatives of Group 2 Metals; X-Ray Structure of 4(py)14>*py (OTf = OSO2CF3) and NMR Spectral Characterisation of (R = SiMe3)

Article abstract of DOI:10.1039/c39940002435

Treatment of M(OTf)2 with 2 MOAr or 2 MNR2 (M = Na or K, Ar = C6H2Bu^t2-2,6-Me-4; R = SiMe3) in thf at 0 deg C affords 4, (M = Sr 5 or Ba 6), (M = Ca 7 or Sr 8) or 9; the new compounds 1-3 have been characterised by their NMR spectra in pyridine, and the pyridine adduct of 3 also by X-ray diffraction: crystalline 2-OTf)2(μ-OTf)2(μ₃-OTf)4(py)14>*py 10 is unique among metal triflates in having three different bonding modes for the -OTf ligand.
