While similar to the pinacol rearrangement, the semipinacol rearrangement differs from the pinacol rearrangement in that the cation is not formed from a vicinal 1, 2-diol.

Arsenic, especially + 3 As, binds to single, but with higher affinity to vicinal sulfhydryl groups, thus reacts with a variety of proteins and inhibits their activity.
43.
For the Sharpless asymmetric dihydroxylation, which uses osmate for the conversion of a double bond into a vicinal diol, Karl Barry Sharpless won the Nobel Prize in Chemistry in 2001.
44.
The order of migrationary aptitude is a tert-butyl as the best substituent followed by isopropyl then vicinal diol is cleaved by lead tetraacetate to the corresponding ketones and acetic acid.
45.
Goodman also conducted studies to determine the contribution of vicinal ( between two methyl groups ) vs . geminal ( between the atoms in a single methyl group ) interactions to hyperconjugation.
46.
Like other such concepts as exo or endo, the description " vicinal " helps explain how different parts of a molecule are related to each other either structurally or spatially.
47.
For instance, if a word has an " O " in it, to be a vicinal it must also have an " N " and / or a " P ".
48.
Access is only possible via a vintage streetcar, a remnant of the country's once extensive vicinal tramway system, which departs from the center of Han-sur-Lesse.
49.
The oxidation can be stopped at the vicinal diol rather than full cleavage of the alkene by using milder ( dilute, lower temperature ) KMnO 4 or with osmium tetroxide or other oxidants.
50.
In 1970 Brulin directed " Saboo ", the first production of Th��tre Laboratoire Vicinal with Fr�d�ruc Flamand ( Plan K, Charleroi Danse now in Marseille ) which caught the attention of Maurice B�jart
