N-Hexanethiol

The amines, tributyl phosphine, n-hexanethiol, NaCN, and KCN were obtained from standard commercial sources. The CN source in CDC13 and CD2C12 was NBu4CN which was prepared by literature methods (18). 

Effect of Axial Ligand. In addition to cyanide ion and piperidine, autoreduction was observed for the following potential ligands—primary, secondary, and tertiary amines pyridine n-hexanethiol and tributyl phosphine. 

Other Systems. Alkyl Thiols. The reduction of hemin with ethane-thiol has been suggested to occur by a free radical mechanism on the basis of product analysis (II). The reaction of n-hexanethiol with TPPFeCl in DMSO carried out in the ESR cavity gives rise to the signal illustrated in Figure 7. These are preliminary results, and the spectrum is of poor quality and probably reflects some saturation from the low steady-state concentration of the radical. Nevertheless the signal only appears during the autoreduction of the iron porphyrin and again indicates that the autoreduction occurs by a free radical pathway.

Their measurements revealed no significant change of the dielectric anisotropy at the same reduced temperatures (TIso/N — T), which our group was able to confirm in related experiments using mixtures of 5CB doped with hexanethiol-capped gold nanoparticles [298].

Figure 947 CVs recorded on hexanethiol-capped PbS nanoparticles in acetonitrile. Peaks marked (1), (n), and (ni) are attributed to the reversible reduction of PbS. Anodic peaks marked (IV) and (V) are attributed to the oxidation and stripping of Pb from the electrode. Reprinted with permission from reference (137). Copyright 2000, American Chemical Society.

Chan et al. studied bulk reaction of hexanethiol (5 mmol) with hexyl acrylate (5 mmol) in the presence of 0.43 M hexylamine (p/C = 10.56), -dipropylamine (p/C3 = ll), and NEtj (pfC = 10.75) under ambient condition for 500 s. After 500 s, reaction with hexylamine showed approximately 95% conversion, n-dipropylamine showed approximately 60% conversion, and NEtj showed less than 1% conversion. These amines have almost the same p/T, but there is a huge difference in their kinetic profiles. Apart from these amines, they also studied various weak nucleophiles, which have varying basicity, such as pyridine (p/C3 = 5.14), aniline (pA3 = 9.34), and l,8-bis(dimethylamino)naphthalene (a proton sponge with pA = 12.1), and found that they yield less than 1% conversion. Based on these observations, the catalysis was attributed to the kinetic...
