Cook, Earl W. F. published the artcileSulfur-containing DalPhos ligand variants: synthesis and application in Buchwald-Hartwig amination, Recommanded Product: 4-(2-(Di(adamantan-1-yl)phosphino)phenyl)morpholine, the publication is Canadian Journal of Chemistry (2015), 93(3), 326-333, database is CAplus.
New P,S-DalPhos ligands Ad2PXSAr (L3-L6; Ad = 1-adamantyl, X = 1,2-C6H4; Ar = alkylphenyl) and Ad2PX1N(CH2CH2)2O (X1 = 3,2-thiophenediyl) featuring pairings of phosphorus and sulfur donor groups as well as new sulfur-containing analogs of the previously reported P,N-ligands Me-DalPhos and Mor-DalPhos, featuring a 2,3-disubstituted thiophene backbone. Palladium organometallic phosphine-thioether and phosphine-amine complexes were also obtained and characterized. In examining the catalytic performance of these new sulfur-containing ligands in the Buchwald-Hartwig amination of octylamine, aniline, or ammonia with 4-chlorotoluene, noteworthy differences in reactivity behavior relative to Me-DalPhos and Mor-DalPhos were observed
