A Tetraarylpyrrole-Based Phosphine Ligand for the Palladium-Catalyzed Amination of Aryl Chlorides

A tetraarylpyrrole-based phosphine ligand L1 in combination with Pd(dba)2 provided a catalyst for the Buchwald-Hartwig amination reaction. A variety of amines were rapidly coupled with aryl chlorides at a Pd loading of 0.5 mol%. The selective monoarylation of aliphatic primary amines was achieved in the presence of 0.8 equiv. water. Comparison experiments were also conducted, which revealed that the catalytic activity of L1 is superior to representative phosphine ligands in the Pd-catalyzed C?N coupling of various amines. (Figure presented.).

PHOSPHINE COMPOUND, CROSSLINKED COMPOSITION, AND MANUFACTURING METHOD OF AROMATIC AMINE COMPOUND

PROBLEM TO BE SOLVED: To provide a phosphine compound capable of constituting a transition metal complex excellent in reaction speed and selectivity as a catalyst. SOLUTION: There is provided a phosphine compound represented by the formula (I). In the formula Ar represents each independently an aryl group which may be substituted, R1 represents each independently a linear, branched or cyclic alkyl group, R2 represents each independently a linear, branched or cyclic alkyl group, alkoxy group or aryl group which may be substituted, or neighboring 2 R2 are bound each other to form a ring, and n represents an integer of 0 to 4.

Silver-catalyzed intramolecular chloroamination of allenes: Easy access to functionalized 3-pyrroline and pyrrole derivatives

A 1,10-phenanthroline-ligated cationic silver complex allows the intramolecular chloroamination of allenes with N-chlorosuccinimide using 2,6-lutidine as a base. This process proceeds under mild conditions and can tolerate a variety of functional groups.
