Usage

General Description

N,N'-Dibenzylphthalamide, also known as DBZP, is a chemical compound that is commonly used as a primary antioxidant in the production of natural and synthetic rubbers. It acts as a heat stabilizer and prevents the degradation of rubber materials at high temperatures, making it essential in the manufacturing of tires and other rubber products. Additionally, DBZP has been used as a plasticizer in the production of PVC materials, as well as an intermediate in the synthesis of pharmaceuticals and organic compounds. It is a white or light yellow crystalline powder with a molecular formula of C24H21NO3 and a molecular weight of 367.43 g/mol. Despite its beneficial properties, DBZP may have potential health hazards and environmental impacts, therefore proper handling and safety precautions should be taken during its production and use.

Guanidine cyclic diimides and their polymers

We report the formation and degradation of a unique guanidine cyclic diimide (GCDI) structure and GCDI-based polymers. The GCDI structure is readily formed under mild conditions. The X-ray crystal structure showed that the delocalized π-orbitals in the guanidine plane are significantly disrupted in the GCDI structure. Unlike amine-based imides, the GCDI structure readily degrades into the initial guanidine in protic solvents at ambient temperatures. Furthermore, poly(GCDI)s, a new category of polymers with the GCDI backbones, can be synthesized from guanidines and dianhydrides. Similar to the monomeric GCDIs, poly(GCDI)s are degraded in protic solvents unlike polyimides with high chemical stability.

A phthalimidation protocol that follows protein defined parameters

This work outlines the first phthalimidation protocol suitable for protein labeling and performed in aqueous media at room temperature and neutral pH with no catalyst or co-reagent required. The methodology is suitable for a range of amines and its efficiency was determined with chemoselective and site-selective protein labeling. This journal is

Studies on the Lossen-type rearrangement of N-(3-phenylpropionyloxy) phthalimide and N-tosyloxy derivatives with several nucleophiles

The reaction of N-(3-phenylpropionyloxy)phthalimide (1a) and N-tosyloxy (5a,b) derivatives with nucleophiles was examined and found to give the products via Lossen-type rearrangement. In order to obtain the scope of this reaction mechanism, further studies the reaction of several N-sulfonyloxyimide derivatives with various nucleophiles under similar conditions were carried out and found to afford the corresponding same types of products in high yields.
