T.J. Thurston, R.G. Brererton, D.J. Foord, R.E.A. Escott, Principal components plots for exploratory investigation of reactions using ultraviolet-visible spectroscopy application to the formation of benzophenone phenylhydrazone, Talanta, 63, 757-769 (2004). [Pg.104]

Hydrazone konnen durch Lithium/HMPT reduziert werden. Wahrend man aus 2-Oc-tanon-phenylhydrazon 60% d. Th. 1-Phenyl-2-octyl-(2)-hydrazin neben 8% d. Th. Ani-lin erhalt, entsteht aus Benzophenon-phenylhydrazon ein 1 1%-Gemisch aus Anilin und Benzophenon-imin (Gesamtausbeute 66%)4 ... [Pg.689]

Hydration of the double bond led to a mixture of alcohols, which were separated and heated with potassium hydroxide in diethylene glycol at 225°C in the presence of a trace of hydrazine (H2NNH2) to cause partial demethylation.That was followed by a modified Oppenauer (potassium t-butoxide-benzophenone) oxidation. Then, bromination of the arylketone produced a dibromide that formed a 2,4-dinitro-phenylhydrazone (DNPH) derivative identical to one obtained from 1-bromothe-... [Pg.1298]

A soln. of benzophenone N-methyl-N-phenylhydrazone in methylene chloride added dropwise at 0-5° with ice-water cooling to a stirred soln. of lead tetraacetate in the same solvent, and stirring continued 20-30 min. at room temp. [Pg.77]
