The reaction of 1,1-dibromo-2,3-bis(chloromethyl)cyclopropane with methyllithium leads initially to ring closure to 1-bromo-2-chloromethylbicyclo<1.1.0>butane.Further reaction leads to an unstable compound which reacts with phenylthiol to give 2-vinyl-1-cyclopropyl phenyl sulfide and undergoes thermal rearrangement at <*> -50 deg C to give cyclopentadiene.Strong evidence is presented which suggests that tricyclo<2.1.0.01,3>pentane may be the intermediate.
