Isolation and characterisation of a (-)-sparteine coordinated mixed alkyl/amido sodium magnesiate, a chiral variant of an important utility ate base.
When a 1:1 nBuNa-n,sBu2Mg mixture is treated with two molar equivalents of TMP(H) (TMP=2,2,6,6-tetramethylpiperidide) and one molar equivalent of (-)-sparteine in hydrocarbon medium, a new chiral mixed-metal, mixed alkyl-amide [{(-)-sparteine}.Na(micro-Bu)(micro-TMP)Mg(TMP)] can be isolated.
