Juanes, Olga; De Mendoza, Javier; Rodriguez-Ubis, Juan Carlos published the artcile< Synthesis of macrobicyclic ligands containing pyrazole subunits: the N,N'-bipyrazolyl cryptand>, Category: pyrazoles-derivatives, the main research area is bromomethylbipyrazole cyclocondensation ammonia diazatetraoxacyclooctadecane; pyrazole bromomethyl cyclocondensation ammonia diazatetraoxacyclooctadecane; amination bromomethylpyrazole; cryptand bipyrazolyl; methanamine pyrazolyl.
The cryptands I and II were prepared in 19 and 56% yield, resp., by reaction of 3,3′-bis(bromomethyl)-1,1′-bipyrazole with anhydrous NH3 and 4,13-diaza-1,7,10,16-tetraoxacyclooctadecane, resp., in dry MeCN at 100°. The tripodal pyrazolyl ligands III (R = H, Me, CH2Ph) were prepared analogously in 35, 41, and 39% yield, resp., by reaction of the appropriate pyrazoles IV with anhydrous NH3.
Journal of the Chemical Society, Chemical Communications published new progress about Amination. 17827-61-1 belongs to class pyrazoles-derivatives, and the molecular formula is C6H8N2O2, Category: pyrazoles-derivatives.
