The polysubstituted dienes according to the invention correspond to the general formula: <IMAGE> in which: X denotes a group chosen from the groups SH, SR3, OR3, SeR3, NHR3 and N=R3 in which R3 denotes an aliphatic or cyclic, saturated or unsaturated group containing from 1 to 20 carbon atoms, Y denotes a group chosen from the groups C 3BOND N and <IMAGE> where R4 denotes hydrogen or an aliphatic or cyclic, saturated or unsaturated group containing from 1 to 20 carbon atoms, provided that, when X denotes the group SCH3, Y does not denote the group <IMAGE> and, when X denotes an OR3 group where R3 is an alkyl group containing at least three carbon atoms, Y does not denote the group C 3BOND N, R1 denotes hydrogen, halogen or an aliphatic, substituted or unsubstituted group containing from 2 to 8 carbon atoms, R2 denotes hydrogen, halogen, an aliphatic, substituted or unsubstituted group containing from 1 to 8 carbon atoms or an aromatic, substituted or unsubstituted group containing from 5 to 8 carbon atoms.
