Usage

General Description

Tetraethyl-1,4-benzenediphosphonate is a chemical compound that belongs to the class of organophosphorus compounds. It is used as a flame retardant and a stabilizer in various industrial applications, particularly in the production of plastics, rubber, and adhesives. TETRAETHYL-1,4-BENZENEDIPHOSPHONATE is known for its ability to effectively inhibit the combustion of materials and reduce the spread of flames. It works by releasing phosphorus-based radicals that disrupt the chemical reactions involved in combustion. Tetraethyl-1,4-benzenediphosphonate is also used as a chemical intermediate in the synthesis of other phosphorus-containing compounds. It is important to handle this chemical with caution, as it can be harmful to human health and the environment if not properly managed.

A permanently porous van der Waals solid by using phosphonate monoester linkers in a metal organic framework

A bis(phosphonatemonoester) is employed as a linker in a Zn(ii) metal organic framework. The complex is a layered structure pillared only by vdW interactions between alkyl groups. Nonetheless, permanent pores are formed as confirmed by PXRD and gas sorption analysis.

Fe-MIL-101 modified by isatin-Schiff-base-Co: a heterogeneous catalyst for C-C, C-O, C-N, and C-P cross coupling reactions

A metal-organic framework functionalized with a cobalt-complex is preparedviapost-synthetic modification of Fe-MIL-101-NH2. Initially, Fe-MIL-101-NH2reacted with isatin to produce Fe-MIL-101-isatin-Schiff-base, which can anchor the cobalt by the addition of cobalt acetate. The resulting MOF-Co catalyst is characterized by employing multiple techniques. This new modified MOF acts as a heterogeneous and recyclable catalyst for efficient Ullmann, Buchwald-Hartwig, Hirao, Hiyama and Mizoroki-Heck cross-coupling reactions of several aryl halides/phenylboronic acid/phenyltosylate with phenols, anilines/heterocyclic amines, triethyl phosphite, triethoxyphenylsilane and alkenes and generates the expected coupling products in good to high yields.

Visible-Light photo-Arbuzov reaction of aryl bromides and trialkyl phosphites yielding aryl phosphonates

Aryl phosphonates are functional groups frequently found in pharmaceutical and crop protection agents. For their synthesis via C?P bond formation typically transition-metal-catalyzed reactions are used. We report a visible-light photo-Arbuzov reaction as an efficient, mild, and metal-free alternative. Rhodamine 6G (Rh.6G) is used as the photocatalyst, generating aryl radicals under blue light. Coupling of the radicals with a wide range of trivalent phosphites gives aryl phosphonates in good to very good isolated yields. The mild reaction conditions allow the introduction of a phosphonate group into complex and sensitive pharmaceutically active molecules such as benzodiazepams and nicergoline by the activation of a carbon?halogen bond.
