A mild Pd/C-catalyzed hydrogenolysis of the C-O bond of model compounds representing the dibenzodioxocin motif in lignin using polymethylhydrosiloxane (PMHS) and water as hydrogen sources was developed. The efficiency of the reaction is highly dependent on both water concentration and the addition of a base. The results from mechanistic studies showed that the benzylic C-O bond is cleaved faster than the terminal C-O bond, which only cleaves upon the presence of the neighboring phenol. We propose a hydrogen bond formation between an oxygen atom of an ether group and a proton of a neighboring phenol under the employed mild reaction conditions, which facilitates cleavage of the C-O bond. In the experiment, the researchers used many compounds, for example, 1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0Application of 14425-64-0).
1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Application of 14425-64-0
