Abstract

2-Methyl-3,3-diphenyl-1-(2,4,6-tri-t-butylphenyl)-1,3-diphosphapropene was obtained as a chelate ligand for palladium(II) and platinum(II) complexes. Sulfurization of 2-methyl-1,3-diphosphapropene mainly gave 3-thioxo-1,3-diphosphapropene which bears a PC–PS skeleton and was used as a ligand of transition-metal complexes. A doubly-sulfurized product of the 1,3-diphosphapropene, 1,3-dithioxo-1,3-diphosphapropene, was isolated and characterized. The palladium(II) complexes containing the ligated 1,3-diphosphapropenes were used for catalytic reactions such as cross-couplings and direct conversion of allyl alcohol to allylaniline.

Graphical abstractSeveral 1,3-diphosphapropene derivatives bearing the PC–P or PC–PS skeleton were prepared and used as a chelate ligand for transition-metal complexes. Some palladium(II) complexes were used for catalytic reactions such as cross-couplings and direct aminations of allyl alcohol to allylaniline.Figure optionsDownload full-size imageDownload as PowerPoint slide
