The phosphazane derivatives (L1-3) were readily obtained by reaction of different ratios of PCl3 and PhNH2. The L 1-3 derivatives were found to be efficient ligands in the palladium-catalyzed Suzuki CC coupling reactions in water. It was determined that with the use of L1-3/Pd(OAc)2 system as a catalyst, aryl halides undergo Suzuki cross-couplings with arylboronic acids to give the desired products in moderate to excellent yields.
1,3,2,4-Diazadiphosphetidines as ligand and base for palladium-catalyzed suzukimiyaura, sonogashirahagihara, and homocoupling reactions of aryl halides under heterogeneous conditions in water

scheme or table, p. 1367 - 1373 (2011/02/22)
1,3,2,4-Diazadiphosphetidines as easily prepared, cheap, and air-stable P(III) containing ligands are successfully used for the efficient CC bond formation via SuzukiMiyaura, SonogashiraHagihara, and homocoupling reactions of aryl iodides, bromides, and chlorides. The reactions occur heterogeneously in refluxing water and the nitrogen atoms in these ligands behave as base to exclude the need to add internally base. The ligand together with its Pd(0) complex is easily separated by filtration and reused for several runs.

1,3,2,4-Diazadiphosphetidine-based phosphazane class have been used as a new generation of heterogeneous bidentate P(III) ligands containing nitrogen for base-free Pd(II) catalyzed C-C bond formation through Heck coupling reaction of aryl iodides, bromides and chlorides in water with styrene, n-butyl acrylate, 1-octene, and cyclohexene. The reactions occur heterogeneously in water and homogenously or partially heterogeneously in appropriate organic solvents. The ligand together with its Pd(0) complex is easily separated by filtration and reused for several runs.
