Abstract A sustainable upgrading of renewable bulk materials, obtained by decomposition biomass lignocellulose, could facilitate their use in the industrial production chemicals. Homogeneous ruthenium catalysis plays a fundamental role this area. The review deals with upgradation lignocellulosic molecules through formation new C−C and C−N bonds. Selected examples catalytic bond forming reactions reported until mid 2023, include: (a) dehydrogenative based couplings alcohols, (b) reductive amination carbonyl compounds, (c) direct C−H functionalization (hetero)aromatic compounds. These approaches fulfill requirements sustainability: application occurs without any previous substrate activation, thus reducing waste. New chemicals containing intrinsic molecular structure lignocellulose substrates, showed broad range applications: green fuels, hydrogen carriers, monomers polymers, intermediates fine pharmaceuticals. results discussed inspire reader to improve valorization process, terms bio‐substrate scope as well product complexity, more strategic applications methods.

Abstract Herein, we demonstrated an effective protocol for the regioselective ring opening of epoxides with alcohols. By following this strategy, both α‐alkylated ketones and β‐alkylated secondary alcohols were selectively obtained by changing reaction parameters. Compared to previously reported protocols, methodology was operated using considerably lower base at temperature. Notably, a wide array substrates tolerance different functional groups demonstrated. A series control experiments deuterium‐labelling performed understand catalytic process.

Alcohols are common alkylating agents and starting materials alternative to harmful alkyl halides. In this study, a simple, benign efficient pathway was developed synthesize 1,3-diphenylpropan-1-ols via the β-alkylation of 1-phenylethanol with benzyl alcohols. Unlike conventional borrowing hydrogen processes in which alcohols were activated by transition-metal catalyzed dehydrogenation, work, t-BuONa suggested be dual-role reagent, namely, both base radical initiator, for coupling aromatic The cross-coupling reaction readily proceeded under transition metal-free conditions an inert atmosphere, affording 1,3-diphenylpropan-1-ol excellent yield. A good functional group tolerance observed, leading production various phenyl-substituted propan-1-ol derivatives moderate-to-good yields. mechanistic studies proposed that could involve formation reactive anions base-mediated deprotonation single electron transfer.
