The p-nitrophenoxycarbonyl derivatives give rise to the same cyclisations in the presence of pyridine by the intermediate of carbamyle-pyridinium ion acting as electrophile.doi:10.1002/hlca.19690520129Baudet PCalin MWILEY‐VCH Verlag GmbHHelvetica Chimica Acta...
Abstract The N-(p-nitrophenoxy-carbonyl) and N-(phenylthio-carbonyl) derivatives of α- amino-acyl-hydrazides cyclize in presence of diazomethane, yielding hexahydro-1, 2, 4- triazines with simultaneous formation of p-nitro-anisole or thio-anisole r
The final goal would be the realization of an electro optical modulator. Finally, we also studied multimode laser emission as a potential probe of photopolymerizable media.doi:10.1016/j.oftal.2010.11.018de la Paz, M.FBibliogr
Polyamides 7a and 7b were prepared from α-(4-aminophenyl)-ω-aminopoly(thio-1,4-phenylene)s (3a) by reaction with 1,12-dodecanedioic acid (6) , tribloc copolymers 9 from 3a and 11 aminoundecanoic acid (8) , and multibloc copolymers 10 from 3a, 6 , and 8 . The properties of ...
