Summary: The effect of structural factors on polymer formation versus cyclization is reported. The reaction of sodium sulfide with either 1,4‐dibromobut‐2‐ene 1 or 1,4‐dibromobutane 2 has been carried out in presence of a phase transfer catalyst and it was observed that the former yields polymer, whereas the latter gives cyclic and linear products. Interestingly, trans / cis isomerization takes place during the polymer formation from 1 and a plausible mechanism has also been discussed.The reaction mechanism for unsaturated compound 1 and saturated compound 2 is discussed here.
