We report herein synthesis and antimicrobialactivity of a series of N,N-dibenzyl-cyclohexane-1,2-diamine derivatives. In order to study the structure–activityrelationship of substituted dibenzyl-cyclohexane-1,2-diamine derivatives, 44 structurally diverse compounds were synthesized and tested against Gram-positive and Gram-negative bacterial strains. Among them, compounds 17-20, 26, 37, 38 were found
Novel eight 1,3-dialkylperhydrobenzimidazolinium chloride salts 3a-h were prepared as precursors of N-heterocyclic carbenes by reacting N,N'-dialkylcyclohexanediamine, triethyl orthoformate and ammonium chloride. The salts were characterized spectroscopically and the complexes formed in situ from Pd(OAc)(2) and 3 have been tested as catalysts in homogenous Heck coupling reactions.

independently is a hydrogen atom or a substituted or unsubstituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, allyl, aralkyl, alkaryl, or alkynyl group. The polymer can be provided by introducing a polyimine compound into a system that includes carbanionic (living) polymer. Such polymers can be used in the production of compositions that include particulate fillers.
