Garcia Suarez, Eduardo J. published the artcileNew alkyl derivatives phosphine sulfonate (P-O) ligands. Catalytic activity in Pd-catalysed Suzuki-Miyaura reactions in water, Name: Sodium 3-bromopropane-1-sulfonate, the publication is Dalton Transactions (2007), 2859-2861, database is CAplus and MEDLINE.
Novel phosphine-alkanesulfonate P-O-chelate ligands and their palladium complexes were prepared; the complexes exhibit excellent catalytic activity in Suzuki-Miyaura coupling of aryl bromides and moderate activity in coupling of aryl chlorides with arylboronic acids. Reaction of (2-MeOC6H4)2PLi with Br(CH2)nSO3Na gave bidentate phosphinosulfonates (2-MeOC6H4)2P(CH2)nSO3H (1, 2; n = 2, 3). Complexation of 1 with [Pd2(μ-Cl)2(η1,η2-C8H13OMe)2] gave the palladium(II) complex, [Pd(η1,η2-C8H13OMe)[(2-MeOC6H4)2P(CH2)nSO3-κO,κP]] (1a, C8H13OMe = 6-methoxy-1-cycloocten-5-yl), which structure was confirmed by x-ray diffraction anal. Suzuki-Miyaura coupling of R1Br with R2B(OH)2 catalyzed by Pd(OAc)2/L (L = 1, 2) gave the corresponding biaryls R1R2 (R1 = 4MeCOC6H4, Ph, 4-MeOC6H4; R2 = Ph, 1-naphthyl, 4-FC6H4, 4-MeOC6H4) with >99% yields. The ligands 1 and 2 are air-stable as well as water soluble; the coupling reactions were run in neat water and under microwave heating as well.
