, p. 245 - 248 (1996)
A number of N-substituted aminotriphenylphosphonium tribromides were investigated for their brominating ability of substituted phenols. It was found that t-butylaminotriphenylphosphonium tribromide, I, exhibits a good and a rather high regiospecificity in comparison with the commonly used bromine.

The development of a palladacyclic precatalyst supported by a new biaryl(dialkyl)phosphine ligand (VPhos) in combination with octanoic acid/sodium octanoate as a simple and effective surfactant system provided an improved catalyst system for the rapid con

Pd-catalyzed Suzuki-Miyaura reaction of aryl chlorides was accomplished through the use of an active ferrocene-based triarylphosphine ligand. This air- and moisture-stable ligand was found to be effective for the cross-coupling of aryl halides at room temperature to 115 °C.
Base and cation effects on the suzuki cross-coupling of bulky arylboronic acid with halopyridines: Synthesis of pyridylphenols
Zhang, Huichang,Kwong, Fuk Yee,Tian, Yuan,Chan, Kin Shing
, p. 6886 - 6890 (2007/10/03)
Strong base and large size cation have been shown to accelerate the rate and the yield of Suzuki coupling of a sterically bulky boronic acid with halopyridines in DME for the synthesis of pyridylphenols.
Preparations and Sulfurization Reactions of (2,4-Di-t-butyl-6-methoxyphenyl)phosphine and 1-(2,4-Di-t-butyl-6-methoxyphenyl)-2-(2,4,6-tri-t-butylphenyl)diphosphene
Yoshifuji, Masaaki,An, De-Lie,Toyota, Kozo,Yasunami, Masafumi
, p. 2069 - 2072 (2007/10/02)
A phosphonous dichloride carrying 2,4-di-t-butyl-6-methoxyphenyl as a novel sterically protecting group was prepared and converted to an unsymmetrical diphosphene, which reacted with sulfur to give the corresponding diphosphene sulfide and thiadiphosphira
