Oxygen atom transfer from nitrite mediated by Fe(III) porphyrins in aqueous solution
Khin, Chosu,Heinecke, Julie,Ford, Peter C.
, p. 13830 - 13831 (2008)
Aqueous solutions of the iron(III) porphyrin complex FeIII(TPPS) (1, TPPS = tetra(4-sulfonatophenyl)-porphyrinato) and nitrite ion react with various substrates S to generate the ferrous nitrosyl complex FeII(TPPS)(NO) (2) plus oxidized substrate. When S is a water-soluble sulfonated phosphine, the product is the resulting monoxide. When air is introduced to the product solutions, 2 is rapidly reoxidized to 1; however, even in the absence of air, there is a slow regeneration of the ferric species with concomitant production of nitrous oxide. Thus, in an anaerobic aqueous environment, FeIII(TPPS) catalyzes oxygen atom transfer from nitrite ion to substrates with the eventual formation of N2O. Copyright

The hydroformylation of octene-1 and the removal of Co2(CO) 8 and HCo(CO)4 from the reaction products including commercial C9 OXO-product were studied under biphasic conditions using an aqueous solution of different electr
ORGANIC CHEMISTRY IN WATER (PART V) NUCLEOPHILIC ADDITION OF WATER-SOLUBLE PHOSPHINES ON ACTIVATED ALKYNES: AN EFFICIENT SYNTHESIS OF NEW VINYLPHOSPHONIUM SALTS AND OF SPECIFICALLY DEUTERATED OLEFINS.

Triphenylphosphine m-trisulfonate 1 and triphenylphosphine m-monosulfonate 2 react in water with activated alkynes R-CC-A (A = CO2H, CO2R1, COR2, CHO) affording new vinylphosphonium salts or vinylphosphine oxides or alkenes depending on the pH of the aqueous solution and on the nature of the substituent R.The reactions of 1 or 2 with alkynes bearing an electron-acceptor substituent R give rise to the corresponding trans disubstituted olefins.Specifically mono or dideuterated alkenes are thus obtained in good yields by sequential use of H2O-D2O.When R = H or Alkyl, vinylphosphonium salts or vinylphosphine oxides are quantitatively produced respectively in acidic or in neutral solution.

The metals Mn, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Ag, and Au are present in 24 new water-soluble complexes containing the ligand tris(sodium-m-sulfonatophenyl) phosphane (TPPTS) which were synthesized from readily accessible precursor compounds and were isolated pure by gelpermeation chromatography.Some of these compounds are the first authentic examples of homoleptic TPPTS metal complexes, viz., Ni(TPPTS)3, Pd(TPPTS)3, Pt(TPPTS)4, Ag(TPPTS)2(TPPTS*), and Au(TPPTS)2(TPPTS*) *: P(C6H4-m-SO3-Na+)2(C6H4-m-SO3-)>, each containing one water molecule per sodium ion.It is noted that the homoleptic TPPTS complexes have lower coordination numbers (TPPTS/metal ratios) than those of corresponding complexes of the parent triphenylphosphane (TPP).

Nucleophilic additions of water-soluble phosphines on γ-alcynic acids afford new vinylphosphonium salts which are easily transformed into specifically deuteriated olefins or phosphine oxides by using sequentially H2O or D2O.

Triphenylphosphine m-trisulfonate P(PhSO3Na)3 = TPPTS and triphenylphosphine m-monosulfonate Ph2PPhSO3Na = TPPMS react in water with α,β unsaturated acids affording hydrosoluble phosphonium salts.The conversion is quantitative because water readily protonates the carbanionic intermediate thus displacing the equilibrum towards the right.This nucleophilic addition of hydrosoluble phosphines has been extended to non water miscible activated olefins in biphasic media; depending on the pH, phosphine oxides or phosphonium salts are obtained.When the reactions are carried out in D2O, the addition products are specifically deuterated.
