Usage

General Description

(+)-CIS-LIMONENE 1,2-EPOXIDE is a chemical compound that is a derivative of limonene, which is commonly found in the peels of citrus fruits. This epoxide compound is a cyclic ether with a three-membered ring structure and is typically used as a precursor in the synthesis of other chemicals. It is known for its distinct citrus aroma and is often used as a flavor and fragrance ingredient in various products such as perfumes, soaps, and cosmetics. Additionally, it has been studied for its potential biological and pharmacological properties, including its antimicrobial and anti-inflammatory effects. However, it is important to note that this compound can be a skin and respiratory irritant and should be handled with caution in a controlled environment.

Synthesis and catalytic activity of Mo(II) complexes of α-diimines intercalated in layered double hydroxides

The two layered double hydroxides ZnAl-LDH and MgAl-LDH were functionalized with bis(4-HOOC-phenyl)-acenaphthenequinonediimine) (H2BIAN), leading to the intercalation of its dianion, which in a second step reacted with [Mo(CO)3X2(NCMe)2] (X = I, Br), affording four new materials. These materials and the two complexes [Mo(CO)3X2(H2BIAN)2] (X = I, Br) were tested in the olefin epoxidation reaction with substrates cis-cyclooctene, styrene, 1-octene, trans-hex-3-en-1-ol, and R-(+)-limonene, using tert-butylhydroperoxide (tbhp) as oxidant. The new catalysts were particularly good for cis-cyclooctene and styrene (100% conversions) and at least one heterogeneous catalyst was comparable to the homogeneous ones in the epoxidation of 1-octene and trans-hex-3-en-1-ol. The homogeneous catalysts were the best to oxidize R-(+)-limonene (higher conversions).

New heterogeneous catalysts with Mo(II) intercalated in layered double hydroxides

The Mo(II) complexes [MoX2(CO)3(BDC)] (X?=?I, Br; H2BDC?=?2,2′-bipyridine-5,5′-dicarboxylic acid) were immobilized by intercalation in two layered double hydroxides (LDH), containing Zn/Al (synthesized) and Mg/Al (commercial), as shown by infrared and13C solid state NMR spectroscopies, and X-ray powder diffraction. Their catalytic activity was studied in olefin oxidation, using as oxidant tert-butylhydroperoxide (tbhp), and was compared with the activity of the related [MoX2(CO)3(bpy)] complexes (bpy?=?2,2′-bipyridine). cis-Cyclooctene, styrene, 1-octene, trans-hex-3-en-1-ol, and R-(+)-limonene were the substrates tested. All the catalyst showed in average a high selectivity toward the epoxide of each substrate (above 90%, except for styrene), with variable conversions, but none of the heterogeneous catalysts proved to be more active than the homogeneous ones. The same or higher activity in a second catalytic run, as observed in most reactions, suggests a good recycling capability.

Biochar as supporting material for heterogeneous Mn(II) catalysts: Efficient olefins epoxidation with H2O2

A novel type of hybrid catalytic materials [MnII-L?BC] has been developed using biochar (BC) as support material for covalent grafting of a MnII Schiff-base catalyst (MnII-L). The hybrid [MnII-L?BC] materials have been evaluated for an important catalytic process, epoxidation of olefins using H2O2 as oxidant. A number of different substrates were used, with cyclohexene achieving the highest yields. When compared to the non-grafted, homogeneous MnII-L, the hybrid catalysts [MnII-L?BC] show a significant enhancement of the catalytic efficiency i.e. as documented by the increase of Turnover Numbers (TONs) (826 for [MnII-L-SS550ox] and 822 for [MnII-L-SW550ox]) and Turnover Frequencies (TOFs) (551 h?1 for [MnII-L-SS550ox] and 411 h?1 for [MnII-L-SW550ox]). The interfacial catalytic mechanism and the role of the BC support have been analyzed by Raman and Electron Paramagnetic Resonance spectroscopies. Based on these data we discuss a mechanism where the high efficiency of the hybrid materials involves the biochar carbon layers acting as promoters of the substrate and products kinetics. To a broader context, this work exemplifies that biochar-based hybrid materials are potent for oxidative catalysis technologies.
