Manganese dichloride

Mutagenic PGR. More recently, methods have been developed to use the PGR reaction to randomly mutagenize a defined sequence (25). The Taq polymerase used in PGR misincorporates nucleotides in a random fashion if manganese dichloride [7773-01 -5] MnGl2, is included in the reaction buffer during PGR. The Hbrary of mutagenized PGR products can be screened for the desired phenotype. [Pg.237]

Vicinal glycols may be oxidized to the corresponding 17a-hydroxy-20-ketones in reasonable yields by means of chromium trioxide in dimethylfor-mamide in the presence of manganese dichloride, or by treatment with dimethyl sulfoxide-acetic anhydride. ... [Pg.184]

It is used to make oxygen in laboratories. One has to heat a mixture of manganese dioxide and an alkaline chlorate. This reaction, which is known for not being dangerous and often used in lectures, gives rise to anhydrous manganese dichloride which reacts explosively with potassium or zinc. Detonation of the mixture is known to have led to several accidents. [Pg.203]

Anaqueous manganese dichloride reacts explosively with potassium or zinc. [Pg.203]

Zinc gives an explosive reaction with manganese dichloride, whereas with calcium chloride, which was in a galvanised iron container, the detonation is blamed on the overpressure created by the release of hydrogen, which is formed in these conditions. [Pg.209]

Different primary, secondary aryl or heteroaryl manganese bromides 519 were prepared by reaction of activated manganese [prepared form manganese dichloride, lithium and a catalytic amount (15%) of 2-phenylpyridine as electron carrier, in THF] with the corresponding brominated compounds 516. These intermediates react with different electrophiles in THF at 0°C with or without copper chloride, to yield the corresponding products 20 (Scheme 144). ... [Pg.731]

Repeated subcutaneous or intraperitoneal injection of manganese dichloride caused increased incidences of lymphosarcomas in mice. Chronic oral exposure of rats to manganese sulfate led to a slight increase in pancreatic tumors that was not dose responsive." There is no information relating manganese exposure to cancer occurrence in humans." Genotoxic assays have yielded mixed results."... [Pg.434]
