- Convenient crystalline source of 1,3-butadiene, which is generated on heating to about 110oC: Rec. Trav. Chim., 61, 785 (1942). For an example of its use in the Diels-Alder reaction, see: Org. Synth. Coll., 6, 454 (1988).
- Lithiation occurs at the 2-position; subsequent alkylation and thermal extrusion of SO2 gave a polyene intermediate in a synthesis of the taxane ring system: J. Org. Chem., 62, 2957 (1997).
- In the presence of Pd(OAc)2, couples with aryldiazonium fluoroborates to give 3-aryl-4-sulfolenes which are readily isomerized with triethylamine to the 3-aryl-3-sulfolenes, providing a source of the corresponding 2-arylbutadienes: Synth. Commun., 26, 231 (1996).
