Methyl glyoxal characteristics

Treatment of methyl sulfoxide solutions of D-mannose or other sugar phenylhydrazones or melibiose phenylosazone with potassium tert-butoxide and a trace of oxygen at room temperature showed no evidence of the paramagnetic species characteristic of glyoxal bis(phenylhydra-... [Pg.98]

Methyl selenien-2-yl glyoxal,118 the simplest a-diketone of the selenophene series, has been obtained in two ways by oxidation of 2-propionylselenophene by selenium dioxide and by hydrolysis of the product resulting from nitrosation of that ketone. Its UV spectrum has three characteristic maxima (Amax 277, 283, and 310 mp). When... [Pg.34]
