Solid state 13C cross-polarisation/magic angle spinning n.m.r. spectroscopy of titanium and magnesium chloride complexes with ethyl acetate

Abstract

Two complexes of ethyl acetate with metal chlorides, [TiCl₄(MeCO₂Et)]₂ and [MgCl₂TiCl₄(MeCO₂Et)₄] were examined by solid-state ¹³C CP/MAS n.m.r. spectroscopy and the isotropic ¹³C chemical shift of the carbonyl carbon was found to be relatively insensitive to co-ordination, though large changes of up to 41 p.p.m. were seen in the σ₂₂ component of the chemical shift tensor.
