Abstract
Several methyl-substituted allylic lithium compounds have been prepared by CH3Li cleavage of their corresponding bis (methyl) bis (allylic) stannanes. Low-temperature 13C and proton NMR studies of 1: 1 complexes of these allylic lithium compounds with TMEDA establish their structures. NMR line shape changes with temperature provide barriers to rotation. Results are listed in order as follows (allyl substituents, compound number, ...
