more sterically hindered organolithiumcompounds. Alkyl groups adversely affect the stability of organolithiumcompounds when attached to the carbon bearing the negative charge, but the extent of this effect is highly dependent on the nature of the rest of the substituents attached to the anionic center. Quantitative data on the stabilization imparted to organolithiumcompounds by Li-O and Li-N chelation
