Here we report a silver-catalyzed alkynyl carbene insertion into β-ketocarbonyls using alkynyl N-nosylhydrazones as alkynyl carbene precursors, which provides access to trisubstituted allenyl ketones. This reaction represents the first example of an alkynyl carbene insertion into a C-C σ bond, affording products homologated with an sp2 carbon center. The products are useful substrates for further transformations. Experimental investigations and theoretical calculations suggest the reaction proceeds through a stepwise enol cyclopropanation/retro-aldol pathway.
Triboluminescence of centrosymmetric lanthanide β-diketonate complexes with aggregation-induced emission

Triboluminescence (TL) is a form of light emission induced upon mechanical forces on the material. However, our understanding of this phenomenon is still unclear and more examples are therefore needed in order to elucidate its mechanism. In this work, two

Reaction of acetylacetone with acyl chlorides in the presence of SmI3 gave β-diketones RCOCH2COCH3 (I) or RCOCH2COR (II) in good yields under mild and neutral conditions.
