Chemical Reaction Classifications

Two strategies for synthesizing N-cyclohexyl-acetamide are shown below. The first is the classic Ritter reaction and the second is a Ritter-type CH amination of an unactivated sp3 carbon center that uses copper(II)bromide, zinc(II)triflate, and Selectfluor®. The authors claim that two equivalents of Selectfluor® are needed.

Reaction of quinoline with copper(II) bromide and DBr in D2O yielded the partially deuterated 2 (Scheme 1). Reaction of quinoline with D2O and PtO2 at elevated pressure and temperature effected deuterium/hydrogen exchange and allowed synthesis of d7-quinoline (Scheme 2). The exchange reaction was conducted three times to ensure deuteration levels greater than 95% as measured by 1H-NMR using dioxane as an internal integration standard. Subsequent reaction of d7-quinoline with CuBr2 under the same conditions yielded the perdeuterated salt, 3. Powder X-ray diffractograms of 2 and 3 were compared to the parent, protonated compound, 1, and indicated that the materials were isomorphous.

Copper(II) bromide (0.111 g, 0.50 mmol) was dissolved in 10.0 ml of 1-propanol with warming resulting in a dark red solution. 2,3-Dichloropyridine (0.148 g, 1.0 mmol) was then dissolved in 4.0 ml of 1-propanol. The 2,3-dichloropyridine solution was then added to the copper(II) bromide solution. The solution was left on the desktop for slow evaporation. After 14 days, a mass of black thin rectangular crystals was present in a minimal volume of solution. These crystals were isolated by vacuum filtration and washed with a small amount of 1-propanol to give a 62.8% yield (0.163 g). IR: 3089 w, 3068 w, 1590 w, 1578 m, 1555 w, 1429 w, 1412 m, 1399 s, 1255 w, 1221 m, 1165 s, 1128 w, 1075 s, 1035 w, 985 w, 938 w, 806 s, 792 s, 774 m, 716 s 691 m.

Atom transfer radical polymerization (ATRP) was used for all brush syntheses [23,24]. The activating catalysts for polycation syntheses were copper(I) chloride (Aldrich, 99%) for PDMAEMA brushes and copper(I) bromide (Aldrich, 99%) for PDEAEMA. CuCl was purified before use by stirring overnight in glacial acetic acid before being filtered and washed with ethanol and diethyl ether a few times and then left to dry under vacuum. Copper(II) bromide (Aldrich, 97%) was used as the deactivating catalyst. The ATRP ligand for polycation brush synthesis was 2,2ʹ-bipyridyl (bipy; Aldrich, 99%). The solvent for DEAEMA brush synthesis was a mixture of deionized (DI) water and methanol, whereas DI water and acetone were used for synthesizing PDMAEMA brushes. CuBr, CuBr2, bipy, acetone, methanol, DI water, 2-(dimethylamino)ethyl methacrylate (DMAEMA; Aldrich, 98%), and 2-(diethylamino)ethyl methacrylate (DEAEMA; 99%, Aldrich) were all used as received. Solid species were degassed for between 10 and 30 min, and liquids were purged under nitrogen for 20 min.
