Thiophosphoryl-, Thiophosphoryloxy-, and Thiophosphorylamino-Benzene Derivatives as Novel Classes of Hybrid Pincer Ligands
摘要:
The synthetic approaches to novel families of SCE (E = S',N,O) hybrid pincer-type ligands bearing thophosphoryl, thiophosphoryloxy, and thiophosphorylamino groups in various combinations with thiophosphoryl-, thiocarbamoyl-, and imine- (including that of benzothiazole ring) donating functions have been developed. All of the ligands readily undergo direct cyclometallation (metal = Pd(II), Pt(II)) to afford 5,5- or 5,6-membered pincer complexes. Palladium complexes displayed from high to excellent catalytic performance in the Suzuki cross-coupling reaction of aryl bromides and phenylboronic acid and the higher asymmetry for a complex served as a factor of its higher catalytic activity.

Cross-coupling between diphenylphosphine oxide and halogenated benzoic acids catalyzed by Pd/C in water is a green, simple and fast protocol to obtain water-soluble tertiary phosphine oxides without the addition of ligands and additives. Low reaction times, microwave irradiation, and high substrate scope make this method general and excellent for lab- and large-scale synthesis without the need to use organic solvents for neither reaction nor workup.

Abstract Hydrolysis of quaternary arylphosphonium zwitterions bearing COO− and those in situ generated from the corresponding salts bearing Ac or OH at the aryl ring by using excess t-BuOK and stoichiometric water affords tertiary arylphosphine oxides in moderate to excellent yield, in contrast to hydrolysis of these zwittertion or salts in aqueous NaOH that mainly provides phosphine oxides with the
