A new hybrid phosphine ligand for palladium-catalyzed amination of aryl halides

A new hybrid phosphine was designed. The phosphine combines two common structural characteristics found among the effective phosphine ligands reported recently, namely, three tert-alkyl substituents binding to the phosphorus and an aryl group at an appropriate position. A hybrid phospine/palladium system is versatile and effective for the coupling reaction of various aryl halides with primary and secondary amines including carbazole.

Bu2SnIH-promoted proximal bond cleavage of methylenecyclopropanes and successive radical cyclization and/or Pd-catalyzed coupling reaction

The unprecedented regioselective hydrostannation of methylenecyclopropanes to give vinyltins was achieved using dibutyliodotin hydride (Bu2SnIH), which could be applied to intramolecular radical cyclization. Copyright

PHOSPHINE COMPOUND, INTERMEDIATE, PALLADIUM-COMPLEX, AND USE THEREOF

Palladum-phosphine complexes obtained by reacting a 5 compound of formula (1) below with a palladium compound: F(I) (wherein Ris a hydrogen atom, an alkyl group, a cycloalkyl group or a phenyl group which may be substituted; R and R are each, the same or different, an alkyl group, a cycloalkyl group or a phenyl group which may be substituted; R and R are each, the same or different, a hydrogen atom, an alkyl group, a cycloalkyl group or a phenyl group which may be substituted; R, R, R and R are each, the same or different, an alkyl group, a cycloalkyl group, a phenyl group which may be substituted, an alkoxyl group, a dialkylamino group, a halogen atom, a phenyl group, a benzyl group, a naphthyl group or a halogenated alkyl group; R and R, R and R may be combined to form, each, a fused ring, a trimethylene group, a tetramethylene group or a 20 methylenedioxy group; p, q, r and s are each an integer of 0 to 5; and p + q, and r + s are each in the range of 0 to 5.), which is a novel and efficient catalyst for manufacturing various useful compounds.

Chloropalladation of Phenyl-Substituted Methylenecyclopropanes

The chloropalladation reactions of methylenecyclopropanes bearing phenyl substituents on the cyclopropane ring are shown to involve 1,3 addition of the elements of Pd-Cl to the organic molecule, with cleavage of the 2,3 ? bond of the ring.Chloropalladatio
