A hydrofluoroether compound comprises two terminal, independently fluoroalkyl or perfluoroalkyl groups and an intervening oxytetrafluoroethylidene moiety (—OCF(CF
3
)—) bonded through its central carbon atom to an alkoxy- or fluoroalkoxy-substituted fluoromethylene moiety (—CF(OR)—), each of the terminal groups optionally comprising at least one catenated heteroatom.

A robust alcohol amination protocol using common saturated cyclic amines and primary alcohols as starting material is described for synthesis of 29 compounds. The reactions are catalyzed by combination of dichloro(p ‐cymene)ruthenium(II) dimer precatalyst with triphenylphosphine ligand. The catalyst can be precipitated by addition of hexane or cold diethyl ether, followed by isolation of the product

Various tetrahydrofuran-2-ylmethylamines have been prepared in good yields by an efficientone-stepsynthesis utilizing the reaction of tetrahydrofurfurylchloride with different secondary cyclic amines without any catalyst. The compounds were tested for their in vitro affinity for the (α4)2(β2)3 and α7* nicotinic acetylcholine receptor (nAChR) subtypes. Pyrrolidine, piperidine and azepane containing

Copper-catalyzed alkeneamino oxygenation reactions using O-acylhydroxylamines have been achieved for a rapid and modular access to diverse 1,2-amino oxygen-containing molecules. This transformation is applicable to the use of alcohols, carbonyls, oximes, and thio-carboxylic acids as nucleophiles on both terminal and internal alkenes. Mild reaction conditions tolerate a wide range of functional groups
