Cyclopentadiene adds to the substituted and electronically activated double bond of bicycloocta-2,5-diene-2,3-dicarboxylic anhydride with pronounced endo selectivity.Only two of the four possible stereoisomers were formed.The stereochemical course of the reaction was determined by X-ray crystallography and by a combination of chemical and sppectroscopic techniques.

, (2008/06/13)
Compounds of and compositions comprising specific salts of saturated [2.2.2] dicarboxylate in order to provide highly desirable properties within thermoplastic (e.g., polyolefin) articles are provided. The inventive salts and derivatives thereof are useful as nucleating and/or clarifying agents for such thermoplastics, are easy to produce and handle, and relatively inexpensive to manufacture. Such compounds induce high peak crystallization and improved stiffness within thermoplastics. Also, thermoplastic compositions comprising such novel nucleating agents exhibit improved heat distortion properties and clarity levels in comparison with the closest unsaturated salt nucleating agents. Thermoplastic additive compositions and methods of producing thermoplastics with such compounds are also contemplated within this invention.
