Differential NMR Shielding by Phenyl, Assigned from Chemical Labelling and (Z,E) Equilibration

Unequivocal NMR assignments of the (E,Z) isomeric pairs 3 and 8 are possible by (Z,E) equilibration.Deprotonation of 2-methyl-1-phenylpropene (1) with n-BuLi under any conditions gives only a single allyl-metal derivative 2.Methylation of the latter gives

2-Methyl-1-phenyl-1-propenyllithium. A Vinyllithium Derivative Showing Catalyzed Transmetalation

Full preparative and kinetic details are given for the apparent vinyl-to-allyl anion rearrangement of the title compound 1.The rapid and quantitative formation of the allyllithium derivative 7 is shown to be catalyzed by 2-methyl-1-phenyl-1-propene (2).An intermolecular transmetalation mechanism with de-aggregation and ionization steps is suggested to explain the orders of reaction, parameters of activation, and solvent dependency.
