General Description

2-Butynedioic acid diallyl ester, also known as diallyl maleate, is a chemical compound that is used in various industrial applications. It is a colorless to pale yellow liquid with a pungent odor, and it is commonly used as a crosslinking agent in the production of unsaturated polyester resins. 2-Butynedioic acid diallyl ester is also utilized as a comonomer in the production of maleate-based polymers and copolymers, as well as an additive in adhesives, sealants, and coatings. Diallyl maleate is known for its ability to improve the flexibility, strength, and durability of the materials it is used in, making it a valuable ingredient in the manufacturing of a wide range of products. However, it is important to handle this chemical with care, as it can be hazardous to health and the environment if not used properly.

Modular functionalization of carbon nanotubes and fullerenes

A series of highly efficient, modular zwitterion-mediated transformations have been developed which enable diverse functionalization of carbon nanotubes (CNTs, both single-walled and multi-walled) and fullerenes. Three functionalization strategies are demonstrated. (1) Trapping the charged zwitterion intermediate with added nucleophiles allows a variety of functional groups to be installed on the fullerenes and carbon nanotubes in a one-pot reaction. (2) Varying the electrophile from dimethyl acetylenedicarboxylate to other disubstituted esters provides CNTs functionalized with chloroethyl, allyl, and propargyl groups, which can further undergo SN2 substitution, thiol addition, or 1,3-dipolar cycloaddition reactions. (3) Postfunctionalization transformations on the cyclopentenones (e.g., demethylation and saponification) of the CNTs lead to demethylated or hydrolyzed products, with high solubility in water (1.2 mg/mL for MWCNTs). CNT aqueous dispersions of the latter derivatives arestable for months and have been successfully utilized in preparation of CNT-poly(ethylene oxide) nanocomposite via electrospinning. Large-scale MWCNT (10 g) functionalization has also been demonstrated to show the s calability of the zwitterion reaction. In total we present a detailed account of diverse CNT functionalization under mild conditions (60°C, no strong acids/bases, or high pressure) and with high efficiency (1 functional group per 10 carbon atoms for SWCNTs), which expand the utility of these materials.
