摘要	C-H methylation is an attractive chemical transformation for C-C bonds construction in organic chemistry, yet eff icient methylation of readily available (bio-)alcohols in water using methanol as sustainable C1 feedstock is limited. Herein, yolk-shellstructured mesoporous carbon nanospheres encapsulated Ir nanocatalysts (Ir@YSMCNs) have been synthesized for this transformation. Monodispersed Ir clusters (ca. 1.0 nm) w ere in situ encapsulated and spatially isolated within YSMCNs by a silicaassisted sol-gel emulsion strategy. A selection of (bio-)alcohols (19 examples) was selectively methylated in aqueous phase with goodto- high yields over the developed Ir@YSMCNs. The improved catalytic eff iciencies in terms of activity, selectivity together w ith the good stability and recyclability were contributable to the ultrasmall Ir clusters with oxidation chemical state as a consequence of the conf inement ef fect of YSMCNs w ith interconnected nanostructures.
