“…Although previously the sensitivity of P−N bonds in the presence of metal ions has been noted, this is the first example of a simultaneous desulfurization and hydrolysis of P−N bonds at ambient temperature. Previous examples of cleavage of sulfur from the PS moiety involved the reaction of RP(S)Cl 2 with Na 2 Fe(CO) 4 . To prepare 2 by a direct process , we have reacted methylphosphonic acid with CuCl 2 in the presence of 3,5-dimethylpyrazole.…”

However, while 3 has been formed in this reaction as a major product, there was no evidence for the formation of 2.…”

The reaction of methylphosphine sulfide, MeP(S)(3,5-Me2Pz)2, 1, with anhydrous CuCl2 affords a tetranuclear copper cluster[Cu2Cl2(3,5-Me2Pz)3(MePO3)]2, 2, and a dinuclear compound Cu2Cl4(3,5-Me2Pz)4, 3. This reaction involves a metal-assisted desulfurization along with concomitant hydrolysis of P-N bonds. The X-ray structures of 1-3 have been determined, and the crystal parameters for these are the following. 1: space group = C2/c, a = 15.2552(1) A, b = 8.7364(2) A, c = 21.4490(3) A, beta = 93.349(1) degrees, V = 2853.74(8) A3, and Z = 8. 2: space group = P2(1)/n, a = 12.5964(4) A, b = 15.7773(4) A, c = 13.9781(4) A, beta = 116.6280(10) degrees, V = 2483.32(12) A3, and Z = 2. 3: space group = P2(1)/c, a = 8.7137(8) A, b = 13.5493(14) A, c = 11.8847(12) A, beta = 106.179(2) degrees, V = 1347.6(2) A3, and Z = 2. The structure of 2 shows that it comprises two dinuclear copper cores bridged together by two tripodal methylphosphinate, MePO3, ligands. 2 is weakly antiferromagnetically coupled, as revealed by variable temperature magnetic susceptibility measurements.

Die Rontgen-Strukturanalyse von 2 bestatigt das Vorliegen des Liganden Methyl(thioxo)phosphan, der ,,side-on" rnit einem (OC),Mn-Komplexfragment und ,,end-on" uber das P-Atom rnit einer (OC),Mn-Gruppe verkniipft ist. Bei einem Atomabstand von 203 pm sollte die P=S-Funktion deutliche x-Bindungsanteile aufweisen. Die sterisch anspruchsvolle (OC),Mn-Gruppe bedingt eine starke Aufweitung des Mn-P-Mn-Winkels.
