Hydroboration-oxidation reducing agent
WebNi(NHC) complexes have a long history of use in homogenous catalysis and have been thoroughly reviewed for their use in C–C cross-couplings, C–H bond functionalisation, C–X (X = O, N, S, B) bond formation, oligo/polymerisation, and oxidation–reduction reactions. 21,22 This review will not cover these previously mentioned classes of reactions. WebThe I-ALD-CAT delivery system consists of 12 different metal ALD precursor channels, 4 oxidizing or reducing agents, and 4 catalytic reaction feeds to either of the two plug-flow reactors.

http://www.shodor.org/UNChem/advanced/redox/index.html WebThe oxidation is achieved by bubbling ozone into the reaction mixture at low temperatures (-78 o C). The first step is the formation of a cyclic intermediate called molozonide (initial ozonide) which quickly rearranges into the more stable ozonide: In the last step, a reducing agent dimethyl sulfoxide (Zn and Acetic acid are also used) is used.
