One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 119515-38-7, Name is sec-Butyl 2-(2-hydroxyethyl)piperidine-1-carboxylate, formurla is C12H23NO3.

Field-induced slow magnetic relaxation in low-spin S=1/2 mononuclear osmium(v) complexes
Photochemical reactions of (PPh4)[Os-VI(N)(L)(CN)(3)] (NO2-OsN) with piperidine and pyrrolidine afforded two osmium(v) hydrazido compounds, (PPh4)[Os-V(L)(CN)(3)(NNC5H10)] ([PPh4]1) and (PPh4)[Os-V(L)(CN)(3)(NNC4H8)] ([PPh4]2), respectively. Their structures consist of isolated, mononuclear distorted octahedral osmium anions that are well-separated from each other by PPh4+. Their low spin S = 1/2 and L = 1 ground state was confirmed by magnetometry and DFT calculations. Interestingly, both compounds exhibit slow magnetic relaxation under a bias dc-field. These osmium(v) complexes are potentially useful building-blocks for the construction of molecule-based architectures with interesting magnetic properties. In contrast, the structurally related (PPh4)[Os-III(L)(CN)(3)(NH3)] ([PPh4]3), which also has a low-spin S = 1/2 ground state but with a different electronic configuration (5d(5)), does not exhibit slow magnetic relaxation, due to the absence of any orbital moment (L = 0). Furthermore, the structurally different osmium(v) hydrazido compound reported by Meyer, [Os-V(tpy)(Cl)(2)(NNC5H10)](PF6) (4[PF6]), also does not exhibit slow magnetic relaxation due possibly to a change in magnetic anisotropy from axial for [PPh4]1 and [PPh4]2 to planar.
