material, is rarely reported to be directly obtained from biomass sources via thermal catalytic transformation. In this work, we found that NiOOHcatalyst could efficiently catalyze the cleavage of β-O-4 ligninmodelcompounds to phenylacetaldehyde and phenol in water without need of any exogenous hydrogen.
majority. Self-transfer hydrogenolysis (STH) is a promising method to produce valuable chemicals and fuels from lignin by cleaving the β-O-4 bond without exogenous hydrogen, but all the reported work used noble metal-based catalysts. In this work, a highly efficient Ni/C catalyst was derived from a Ni-containing metal–organic framework (Ni-MOF), and its self-transfer hydrogenolysis performance towards

Herein we report the iron-catalyzed beta-C(sp(3))-methylation of primary alcohols using methanol as a Cl building block. This borrowing hydrogen approach employs a well-defined bench-stable (cyclopentadienone)iron(0) carbonyl complex as precatalyst (5 mol %) and enables a diverse selection of substituted 2-arylethanols to undergo beta-C(sp(3))-methylation in good isolated yields (24 examples, 65% average yield).
