A Light(er) Approach for the Selective Hydrogenation of 5-Hydroxymethylfurfural to 2,5-Bis(hydroxymethyl)furan without External H2 was written by Jaryal, Arpna;Venugopala Rao, Battula;Kailasam, Kamalakannan. And the article was included in ChemSusChem in 2022.Formula: C8H10O2 This article mentions the following:
The selective conversion of 5-hydroxymethyfurfural (HMF), a biomass-derived platform mol., to value added chems. can ease the burden on petroleum-based fine chem. synthesis. The active contribution of renewable energy sources along with low cost, environmental friendliness, and a simple reaction system must be adopted for better sustainability. In this context, photocatalytic selective hydrogenation of HMF to 2,5-bis(hydroxymethyl)furan (BHMF) was achieved over P 25 titania nanoparticles without chem. squander. Simultaneously the photo-oxidation of p-methoxybenzyl alc. (MeOBA) to p-methoxybenzaldehyde (MeOBaL), similar to biomass-derived vanillin, was carried out, abolishing the need of addnl. redox reagents. This system put forward the competent employment of photogenerated excitons for the valorization of lignocellulosic biomass to fine chems., which is an urgent requirement for sustainable chem. synthesis. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Formula: C8H10O2).
(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Formula: C8H10O2
