We report the facile preparation of palladacycles as storable arylpalladium(II) reagents from acetanilides via cyclopalladation. The palladacycles exhibit good stability in PBS buffer and are capable of functionalizing a metabolically encoded HPG-containing protein, thus providing a new type of biocompatible organometallic reagent for selectively functionalizing the alkyne-encoded proteins.

background: resistant strains of pseudomonas aeruginosa to imipenem was medical treatment problem, especiallyin burnt units of hospitals. objectives: this study was conducted to evaluate the antimicrobial effect of fe2o3 nanoparticles alone and functionalized with imipenem on p. aeruginosa starins producing metallo b-lactamases (mbl).materials and methods: a disk diffusion method was used to is...
