Purification Methods

Purify it by converting it to the hydrochloride with HCl, then basify it with NH3 and recrystallise it from pet ether (m 62-63o) or from hexane. The hydrochloride M 217.7, m ~255o(dec, from EtOH).

Check Digit Verification of cas no

The CAS Registry Mumber 525-03-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,2 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 525-03:
51 % 10 = 1
So 525-03-1 is a valid CAS Registry Number.

Palladium-catalyzed benzylic arylation of N-benzylxanthone imine

Niwa, Takashi,Yorimitsu, Hideki,Oshima, Koichiro

supporting information; experimental part, p. 4689 - 4691 (2009/05/13)

(Chemical Equation Presented) The direct benzylic arylation of N-benzylxanthone imine with aryl chloride proceeds under palladium catalysis, yielding the corresponding coupling product. The product is readily transformed to benzhydrylamine. Taking into consideration that the imine is readily available from benzylic amine, the overall transformation represents a formal cross-coupling reaction of aryl halide with α-aminobenzyl metal.

The Electrochemical Reduction of Fluorenone Tosylhydrazone: Evidence Consistent with Formation of the Tosyl Nitrene Anion Radical

Galen, Dean A. Van,Barnes, James H.,Hawley, M. Dale

, p. 2544 - 2550 (2007/10/02)

Fluorenone tosylhydrazone (Fl=NNHTs) undergoes one-electron reductive dehydrogenation in DMF-0.1 F (n-Bu)4NClO4 to give hydrogen and its conjugate base Fl=NN-Ts as products.Fl=NN-Ts is subsequently reduced at more negative potential to a dianion radical (Fl=NNTs dianion radical) that is stable on the cyclic voltammetric time scale.On the coulometric time scale or in the presence of added proton donors (pKa ca.29), Fl=NNTs dianion radical decomposes to give FlHNH2 and TsNH2 as the principal products.A pathway is proposed for the reaction of Fl=NNTs dianion radical which involves rate-determining proton abstraction by the nitrogen atom α to the fluorene moiety.Cyclic voltammetric and chronoamperometric data are presented which are consistent with the formation of the tosyl nitrene anion radical as a short-lived, unobserved intermediate.
