Randomly oriented twin domains in electrodeposited silver dendrites

Silver dendrites were prepared by electrochemical deposition. The structures of the Ag dendrites, the type of twins and their distribution were investigated by scanning electron microscopy (SEM), Z-contrast high angle annular dark field transmission electron microscopy (HAADF), and crystallographically sensitive orientation imaging microscopy (OIM). The results revealed that the silver dendrites were characterized by the presence of randomly distributed 180 degrees rotational twin domains. The broad surface of dendrites was of the {111} type. The directions of growth of the main dendrite stem and all branches were of the lt 112> type

Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha

The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by changing shape of the reversing current wave and, hence, the apparent density of powders. The relation of apparent density with particle morphology and structure was illustrated.U radu je pokazana mogućnost dobijanja bakarnih prahova različitih nasipnih masa promenom oblika talasa reversne struje. Uspostavljena je zadovoljavajuća veza između morfologije i strukture čestica praha bakra i nasipne mase praha

Hofmann Rearrangement of Carboxamides Mediated by N-Bromoacetamide

An efficient, one-pot procedure for the Hofmann rearrangement of aromatic and aliphatic amides has been developed. Methyl and benzyl carbamates are produced with N-bromoacetamide in the presence of lithium hydroxide or lithium methoxide, in high yields. -Phenylamino amides gave five-membered cyclic ureas stereospecifically. Side products of aryl or benzyl bromination were minimized. This procedure offers an easy access to various protected amines or diamines, which represent important synthetic precursors.Supplementary material: [http://cherry.chem.bg.ac.rs/handle/123456789/3523

Synthesis of Orthogonally Protected (+/-)-3-Amino-4-anilidopiperidines and (+/-)-3-N-Carbomethoxyfentanyl

The synthesis of orthogonally protected cis- and trans-3-amino-4-anilidopiperidine derivatives has been accomplished in six steps, starting from readily accessible 4-piperidone derivatives. The last three steps, i.e., N-acylation, Hofmann rearrangement, and carbamate cleavage, involved separated (+/-)-cis and (+/-)-trans intermediates. Complete retention of configuration was observed at position 3 of the piperidine ring. Specifically protected positions 1 and 3 at the piperidine scaffold allow for selective deprotection and introduction of diverse substituents at the respective nitrogen sites. The orthogonally protected anilidopiperidines open avenues to potentially pharmacologically active compounds, including opioids and various bivalent ligands for G protein-coupled receptors. In addition, a prototype of a novel class of fentanyl derivatives, possessing a 3-amino group, was synthesized by using the same approach.Supplementary material: [http://cherry.chem.bg.ac.rs/handle/123456789/3249
