Catalytic transformations involving Pd s-alkyl or s-aryl intermediates are widely used in organic synthesis and offer attractive routes to many valuable products. However, the vast majority of these reactions proceed by Pd/Pd mechanisms. As a result, the diversity of structures/bonds that can be constructed is constrained by the limitations of this redox cycle. Recent studies have explored the ...

A new one-pot approach for the synthesis of aryl a-keto ester based on the diazo transfer and oxidation of diazo group is developed. 2005 Elsevier Ltd.

Over the past decades, various methods have be...

C–H borylation of N-heteroarenes is an efficient yet highly challenging route to borylated aromatics. In a recent issue Nature, Leonori and co-workers demonstrated novel strategy toward this end by utilizing boryl-radical-based Minisci-type reaction that shows orthogonal site selectivity transition-metal-catalyzed approaches. Direct aromatic bonds straightforward means accessing diverse arene s...
