The 11 adduct of t-butyllithium and α-methylstyrene (II) has been generated in cyclopentane in the presence of a variety of ether and t-amine ligands as well as unsolvated, giving stable solutions in every case. NMR spectra of the solvated species a

The course of reaction of 1-phenylcycloalkenes, Ph CCH(C H2)n with t-butyllithium in the presence of THF or TMEDA is found to vary with ring size as follows: n 2, polymerization; n 3, allylic deprotonation and addition to the double bond;

The benzylic lithium compounds produced by 1 : 1 addition of t-butyl-lithium to α-methylstyrenes react with O2 to produce radicals which undergo disproportionation via hydrogen atom transfer; these unusual results are ascribed to steric hindrance ab
