A Pd/Cu-catalyzed base mediated domino process of ortho-halo (hetero)aryl carboxaldehydes and propargyl alcs. unexpectedly furnish 2-(hydroxymethylene)indenones in good to excellent yield as a result of a coupling-isomerization-cycloisomerization reaction (CICIR). In addition, the title compounds constitute an interesting class of luminophores with tunable emission solvatochromicity.2-Bromonicotinaldehyde(cas: 128071-75-0Recommanded Product: 2-Bromonicotinaldehyde) was used in this study.
2-Bromonicotinaldehyde(cas: 128071-75-0) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.Recommanded Product: 2-Bromonicotinaldehyde
