[reaction: see text] The synthesis and characterization of a series of symmetric bis-dialkyldiamine-based diazeniumdiolates, RN[N(O)NO(-)Na(+)](CH(2))(x)()N[N(O)NO(-)Na(+)]R', are reported. Preparation of corresponding intramolecular diazeniumdiolates of the form RN[N(O)NO](-)(CH(2))(x)()NH(2)(+)R' with alkyl groups > (CH(2))(4)CH(3) have been shown previously to lack stability. In contrast, sodium-stabilized
Carbamatesderivedfrom various N,N'-disubstituted diamines were synthesized and evaluated as repellents for Aedes aegypti mosquitoes with an in vitro blood-feeding test system. Several compounds were more effective than diethyltoluamide.
N,N'-Bridged-bis[(O and/or N-substituted)-2-alkyl-2-hydroxyethylamines] of the formula ##STR1## are prepared by condensing an epoxide of the formula ##STR2## and a diamine of the formula R'NH-X-NHR'. The products and dicarbanilates, acid-addition salts, N,N'-dioxides and N,N'-diammonium quaternary salts derived therefrom have antibacterial activity in vitro and are useful as antibacterial agents.
N,N'-Bridged-bis[(O and/or N-substituted)-2-alkyl-2-hydroxyethylamines] of the formula ##STR1## are prepared by condensing an epoxide of the formula ##STR2## and a diamine of the formula R'NH--X--NHR'. The products and dicarbanilates, acid-addition salts, N,N'-dioxides and N,N'-diammonium quaternary salts derived therefrom have antibacterial activity in vitro and are useful as antibacterial agents.
