Barium manganate (barium permanganate) [7787-35-1 ] M 256.3, d 3.77. Wash with... [Pg.398]

The standard potential e of reaction (1) is 0.56 volt and of reaction (2) 0.60 volt. By suitably controlling the experimental conditions (e.g. by the addition of barium ions, which form the sparingly soluble barium manganate as a fine, granular precipitate), reaction (1) occurs almost exclusively. In moderately alkaline solutions permanganate is reduced quantitatively to manganese dioxide. The half-cell reaction is ... [Pg.369]

Barium manganate [7787-35-] J M 256.3. Wash with conductivity H2O by decantation until the supernatant gives a faint test for Ba . Remove excess H2O in vac (IMPORTANT), then heat at 100° and the last traces of H2O are removed in a vac desiccator over P2O5. Store over KOH. It disproportionates in hot H2O or dil acid to Ba(MnO2)2 and Mn02, and is a mild oxidant. [7ACS 44 1965 1924-, Inorg Synth 11 56 I 960]. [Pg.368]

Dehydrogenation of 2-imidazolines.1 Barium manganate is superior to MnCK (2, 258) for dehydrogenation of 2-imidazolines to imidazoles (three examples, 75 95% yield). [Pg.16]

Barium manganate (BaMn04) was a little known oxidant in organic synthesis till Firouzabadi et al. published in 1978 83 two foundational papers76 showing that it behaves against alcohols in a similar way as active MnC>2. [Pg.309]

A suspension of ca. 5 20 equivalents—typically 10 equivalents—of dry powdered barium manganate (BaMn04, MW = 256.28) in a ca. 0.02-0.08 M solution of the alcohol in dry CH2Cl2,a is stirred at room temperature1 under an inert atmosphere till most of the starting compound is consumed.0... [Pg.311]
