The reaction of Me2PO2H and Me2AsO 2H with SbCl3, BiCl3, and Bi(NO 3)3·5H2O gave the complexes Sb(Me 2PO2)3, Sb(Me2AsO2) 3, (Me2PO2)2Bi-Cl, Bi(Me 2-AsO2)3, (Me2PO2) 2Bi(NO3), and (Me2AsO2) 2Bi(NO3)·H2O, respectively. The arsinato complexes did not react with the Lewis bases pyridine, Ph3P, and Ph3As in acetone. The compounds Sb(Me2AsO 2)3 and (Me2AsO2) 2Bi(NO3)·H2O reacted to a small extent with nicotinic acid in methanol but Bi(Me2AsO2) 3 gave (Me2AsO2-BiO)x in good yields. (Me2AsO2)2Bi(NO3) ·H2O in methanol quantitatively rearranged to new complexes with the same composition, [(Me2AsO2) 2Bi(NO3)·H2O]' and [(Me 2AsO2)2Bi(NO3)·H 2O]'' in the presence of pyridine. With thiophenol in air, Sb(Me 2AsO2)3 gave PhSSPh and Me2As-SPh (1:1 mol ratio), (Me2AsO2-SbO)x and some Sb(Me2AsO2)3 was reformed, Bi(Me 2AsO2)3 gave (Me2AsO 2-BiO)x, PhSSPh, and Me2As-SPh (1:0.6 mol ratio), whereas (Me2AsO2)2Bi(NO 3)·H2O quantitatively gave PhSSPh, thus acting as a catalyst for the air oxidation of thiophenol.
The Electrophilic Character of Bunsen's Cacodyl Disulfide, Me2As(S)-S-AsMe2, Towards Some Nucleophiles of Groups 15 and 16

The reactivity of Bunsen's cacodyl disulfide, Me2As(S)-S-AsMe2, towards nitrogen, phosphorus(III), oxygen and sulfur(II) nucleophiles was evaluated with the aim at identifying its electrophilic atom. The nitrogen nucleophiles either
