[Synthesis and physicochemical and biological characteristics of phthalazine derivatives].

Further studies in view of obtaining new stable phtalasiniuilides present the synthesis and physico-chemical and biological characterization of certain derivatives obtained through the action of p-phenyl-phenacyl and p-nitro-phenacyl bromides upon R-phtalasine. The structure of the new products was confirmed by physicochemical and spectral analyses. The preliminary biological tests showed a moderate antimicrobial activity of certain studies compounds.
