Usage

General Description

N,N'-diphenylpropane-1,3-diamine, also known as DPPD, is a chemical compound commonly used as an antioxidant in rubber products and as a stabilizer in plastics. It is a white to grayish powder that is slightly soluble in water and soluble in organic solvents. DPPD is known for its ability to inhibit the oxidation of rubber, thereby extending the lifespan of rubber products. It is also used in the manufacture of plastics to prevent them from deteriorating due to exposure to heat and light. However, there is some concern about the potential health and environmental effects of DPPD, and further research is needed to fully understand its impact.

Iridium-Catalyzed Direct Cyclization of Aromatic Amines with Diols

We developed an environmentally friendly iridium-catalyzed direct cyclization of aromatic amines with diols that generates the corresponding N-heterocyclic compounds with water as the sole by-product. Thus, under conditions of 165 °C for 18 hours, the direct cyclization of N -methylanilines with 1,3-propanediol by using an IrCl 3 catalyst with rac -BINAP as a ligand in mesitylene afforded the corresponding tetrahydroquinoline derivatives with yields ranging from 73 to 83%. Under similar reaction conditions, direct cyclization of anilines with 1,3-propanediol produced the corresponding tetrahydrobenzoquinolizine derivatives with yields ranging from 26 to 76%.

Adding value to renewables: A one pot process combining microbial cells and hydrogen transfer catalysis to utilise waste glycerol from biodiesel production

Waste glycerol was converted to secondary amines in a one pot reaction, using Clostridium butyricum and catalytic hydrogen transfer-mediated amination. The Royal Society of Chemistry 2009.

Heterogeneous bimetallic Pt-Sn/γ-Al2O3 catalyzed direct synthesis of diamines from N-alkylation of amines with diols through a borrowing hydrogen strategy

Direct synthesis of diamines has been efficiently realized from the N-alkylation of amines with diols by means of heterogeneous bimetallic Pt-Sn/γ-Al2O3 catalyst (0.5 wt % Pt, molar ratio Pt:Sn = 1:3) through a 'Borrowing Hydrogen' strategy under ligand-free conditions. The present methodology provides an environmentally benign route to diamines.
