Convenient large scale in situ synthesis of 3-(N,N-dialkylamino)-1,1-bis(trimethylsilyl)-propyllithium: source of a new sterically demanding γ-donor functionalized alkyl ligand

Abstract

The addition of Li[CH₂NR₂] to the olefin [Me₃Si]₂CCH₂ yields almost quantitatively the new γ-donor functionalized organolithium compounds (Me₃Si)₂C(Li)CH₂CH₂NR₂ which are used to synthesize the intramolecularly adduct stabilized organo-gallium and -zinc complexes R₂GaC(SiMe₃)₂CH₂CH₂NR₂, {ClZnC(SiMe₃)₂CH₂CH₂NR₂NR₂}₂.
