Abstract

Lithiation of 2-mercaptobenzoxazole, C₆H₄OC(SH)=N, in the presence of tmeda [Me₂N(CH₂)₂NMe ₂] and H₂O produces the monomeric title complex, C ₆H₄OC(...S)...NLi(tmeda)H₂O (1), the first lithiated organic compound containing water as a ligand; this complex exhibits strong hydrogen bonding between one proton of the co-ordinated H₂O and the S^δ- centre of the organic anion, and so provides the first structural model for the well known hydrolytic sensitivity of organolithium compounds in general.
