We herein develop an innovative approach for the decarbonylative silylation using a molecular [Ru(dcbpy)(bpy)2]2+ (dcbpy = 2,2′-bipyridyl-5,5′-dicarboxylic acid; bpy 2,2′-bipyridine) incorporated UiO-67 metal–organic framework (MOFs) (denoted as UiO-67-Ru) powerful heterogeneous catalyst, which is then applied in reaction of abundantly available cinnamaldehydes with silanes under photothermal condition. Mechanistic studies reveal that silane can be absorbed and activated within cavities framework, leading to generation silyl radical. The radical plays key role process further goes through oxidative generate corresponding alkenyl silanes. This work not only develops strategy preparation from highly abundant cinnamaldehyde but also affords useful inspiration on rational design MOFs materials silylation.

Herein, we report sodium iodide (NaI)-catalyzed decarboxylative C–H alkylation of azauracils with N-hydroxyphthalimide (NHPI) esters facilitated by visible light activation catalytic electron donor–acceptor (EDA) complexes. Control experiments and density functional theory calculations suggest that the coupling reaction proceeds via a transiently assembled EDA complex between NHPI ester NaI in N,N-dimethylacetamide solvent. This synthetic method efficiently applies to primary, secondary, tertiary under mild, photocatalyst-free, redox-neutral conditions, achieving high yields desired alkylated azauracils.
