The unique reaction between 4, 6-dimethoxy-5-nitropyrimidine
and methylhydrazine was investigated. The reaction product was
identified as 4-hydrazino-6-hydroxypyrimidine from (a) spectral
data, (b) by direct synthesis of the product via 4-chloro-6-hydroxypyrimidine
and hydrazine, and (c) by conversion of the product to
the known 4-amino-6-hydroxypyrimidine using Raney nickel. The
product was not...
The methanolysis of phosphorus trichloride coordinated to nickel
(0) has been studied. Free phosphorus trichloride reacts with methanol
to give dimethyl hydrogen phosphonate, methyl chloride, and hydrogen
chloride. The reaction involves a rearrangement on phosphorus using
the lone pair, in which the coordination number increases from three
to four. In...
