Article abstract of DOI:10.1016/S0040-4039(98)00447-X

1-Trimethylsilyl-2-phenylcyclopropene (1) was generated from bromo- lithium exchange of 1-bromo-2-phenylcyclopropene followed by treatment with trimethylsilylchloride. Compound 1 underwent ene dimerizations to give endo and exo diners 5 and 6 which would dimerize by coupling reaction to yield a sole tetramer 4.
