A Novel and Versatile Synthesis of 1-Alkyl-, 1-Aryl-, 1-(Alkylamino)-, or 1-Amido-Substituted and of 1,2,6-Trisubstituted Piperidines from Glutaraldehyde and Primary Amines or Monosubstituted Hydrazines

Various primary amines and 1-mono- and 1,1-disubstituted hydrazines were converted into the corresponding N-substituted piperidines in good to excellent yields via the products of double condensations with benzotriazole and glutaraldehyde.Reduction of the 2,6-bis(benzotriazolyl) N-substituted piperidines 4 and 7 with sodium borohydride in tetrahydrofuran afforded N-substituted piperidines.The benzotriazole moieties were also replaced by alkyl groups by reaction with Grignard reagents to produce 1,2,6-trisubstituted piperidines.

Kinetic Effects of an Unusually Large Neutral to Radical Cation Geometry Change. Slow Electron-Transfer Reactions between Alkylhydrazines

High pressure mass spectrometry was used to measure the kinetics for electron transfer between 54 pairs of tetraalkylhydrazines containing acyclic and f-ve- to seven-membered cyclic and bicyclic rings.Rate constants for electron transfer vary between 18 and 0.03 x 10-11 cm3molecule-1s-1 at 550 K.Variable-temeprature mesuremeants were made on five pairs over a 77-120 deg range.The (Me2N)2(1+), (EtMeN2)2 pair gave Ea=2.7 kcal/mol.The association energy for (Me2N)2 was measured at ΔH0=-13.0 kcal/mol near room temperature.These data are combined to estimate an energy separation of about 15.7 kcal/mol between associated (Me2N)2(1+)/(EtMeN)2 dimer complex and the transition state for electron transfer.The observed Bronsted α value of about 0.5 suggests a large barrier to electron transfer, and the kinetics suggests that the components largely retain their original structures in the associated complex, but that significant distortion is required to reach the transition-state geometry.The effect of alkyl group changes on the electron-transfer rate and comparison of these data with solution experiments are discussed.
