New rhodium(I) water-soluble complexes with 1-alkyl-1-azonia-3,5-diaza-7-phospha-adamantane iodides and their catalytic activity

“…1). The cone angle for the first phosphine is 102°1 2,13,16,18 and for mtpa I À it is approximately the same. [18][19][20] Thus properties of complexes with these ligands should depend mainly on their electronic properties.…”

“…The cone angle for the first phosphine is 102°1 2,13,16,18 and for mtpa I À it is approximately the same. [18][19][20] Thus properties of complexes with these ligands should depend mainly on their electronic properties. We describe here rhodium(I) complexes with 1,3,5-triaza-7-phosphatricyclo-[3.3.1.1 3,7 ]decane (tpa) and its alkylazonia derivatives: 1-methyl-(mtpa I À and mtpa Cl À ), 1-ethyl-(etpa I À ) and 1-propyl-1-azonia-3,5-diaza-7-phosphatricyclo[3.3.1.1 3,7 ]decane iodide (ptpa I À )…”

“…Comparatively little work has been carried out on hydrophilic trialkylphosphines. Interesting properties are exhibited by 1,3,5-triaza-7-phosphatricyclo[3.3.1.1 3,7 ]decane (tpa) 10,[12][13][14][15][16][17][18] and 1-methyl-1-azonia-3,5-diaza-7-phosphatricyclo-[3.3.1.1 3,7 ]decane iodide (mtpa I À ) ( Fig. 1).…”

Water-soluble and water-stable Gold(I), Gold(II) and Gold(III) phosphine complexes: The early years

“…The gold(I) TPA complexes [AuX(TPA)] (X = Cl, Br, I, Me) were prepared and, in some cases, structurally characterized [12]. The complexes [AuX(TPA)]·CH 3 CN (X = Cl, Br) form dimers with short Au ...…”

Some recent highlights in gold chemistry

“…It has been shown that the luminescence has its origin in the nature of the ligands, in the geometry around the metal centre, and in the presence of metal-metal interactions. In mononuclear gold(I) complexes the luminescence has been associated with a trigonal, non-centrosymmetric structure obtained either through intermetallic interactions or three-coordination associated with a metal centred (MC) pz→ds phosphorescence (54). Other possible absorption modes, such as ligand centred (LC) or ligand to metal charge transfer (LMCT), are also observed depending upon the types of ligands present.…”
