Synthesis and basicity of 4-amino-2-phenylquinazolines
Zielinski, Wojciech,Kudelko, Agnieszka
, p. 895 - 899 (2007/10/03)
A new group of 6-and 7-substituted compounds of 4-amino-2-phenylquinazoline were synthesized by reaction of N-arylbenzimidoyl chlorides with cyanamide in the presence of TiCl4. The products were identified by spectroscopic methods, their dissoc
Synthesis of 4-Aminoquinazoline Derivatives
Zielinski, W.,Mazik, M.
, p. 489 - 498 (2007/10/02)
The reaction of N-phenylimidoyl chlorides (2) with cyanamide and N,N-dimethylcyanamide (4) was studied.At the first stage, linear products like 1-amino-1-chloro-3,5-diphenyl-2,4-diaza-1,3-butadienes (6) were obtained.They underwent cyclization to 4-aminoq
AMIDINES. PART IX. INFLUENCE OF SUBSTITUTION AT IMINO AND AMINO NITROGEN ATOMS ON THE BASICITY OF N,N'-DIPHENYLBENZAMIDINES
Oszczapowicz, Janusz,Raczynska, Ewa,Orlinski, Ryszard
, p. 2031 - 2037 (2007/10/02)
A series of 15 unreported N1-metylo-N1,N2-diphenylbenzamidines containing two different substituents at phenyl rings have been synthesized and their pKa values in 99.8percent ethanol were determined.It was found
