Transition‐metal‐catalyzed coupling reactions that involve the direct functionalization of insert C−H bond represent one of the most efficient strategies for forming carbon‐carbon bonds. Herein, a palladium‐catalyzed intramolecular C−H bond arylation of triaryl phosphates is reported to access seven‐membered cyclic biarylphosphonate targets. The reaction is achieved via a unique eight‐membered palladacyclic intermediate and shows good functional group compatibility. Meanwhile, the product can be readily converted into other valuable phosphate compounds. [ABSTRACT FROM AUTHOR]

We have developed a simple and effective method for the C-3 arylation of phosphorus-containing indole compounds in the presence of CuI under mild conditions. This reaction provides a reliable method for the modification of ligands. [ABSTRACT FROM AUTHOR]

A palladium-catalyzed, temporary P(O) directing group assisted C–H bond arylation of carbazoles was achieved. The release of the directing group occurs spontaneously in the reaction and the mechanistic studies indicate that acid is essential for N–P bond cleavage. [ABSTRACT FROM AUTHOR]

An efficient metal-free tandem intramolecular oxidative C−H amination and iodization of phosphinamide was performed and a series of new phosphorus heterocyclic compounds was obtained. This method provides a concise and highly valuable pathway for the synthesis of difunctional atropoisomeric P-stereogenic phosphinamides. [ABSTRACT FROM AUTHOR]

Highly selective arylation catalyzed by palladium and directed by the acetamino group provides an efficient and practical protocol for constructing unique biaryl scaffolds, which could be further transformed into different structural units found in a range of natural products. 1 Introduction 2 Highly Regioselective Halogenation 3 Highly Regioselective Arylation 3.1 With Arylboronic Acids 3.2 With Trialkoxyarylsilanes 3.3 With Simple Arenes 3.4 Further Transformations 4 Conclusion [ABSTRACT FROM AUTHOR]

This oxidative arylation is suitable for a variety of α-amino acid derivatives, e.g. esters and amides including peptides. [ABSTRACT FROM AUTHOR]

A palladium-catalyzedallylic C–H arylation reaction withelectron-deficient arenes with high regio- and stereoselectivity isreported. This work represents the first successful use of 1,1′-bi-2-naphtholas the ancillary ligand in allylic C–H activation, which isthe key factor for chemoselectivity. Furthermore, high selectivityallylic C–H acetoxylation and amination were also successfullyachieved under the same catalytic system. [ABSTRACT FROM AUTHOR]

Abstract: A new protocol for the synthesis of polysubstituted isocoumarins from 2-iodobenzoic acid and β-diketone compounds has been developed. The occurrence of C-arylation cyclization reaction in transition-metal-free systems and ortho-induced substrates has been exploited. Reactions using these inexpensive conditions have displayed high functional group tolerance and excellent yields. [Copyright &y& Elsevier]
