Polymer supported vanadium complexes as catalysts for the oxidation of alkenes in water
Hsiao, Ming-Chieh,Liu, Shiuh-Tzung
, p. 61 - 66 (2010)
Polymer supported vanadium complexes (denoted as c-PMA n -V) were prepared by the complexation of vanadium ions onto a cross linked polyacrylate. c PMA n -V can catalyze the oxidative cleavage of olefins with a large excess of t-butyl hydroperoxide (TBHP) or bishydroxylation of olefins with 4 eq. of TBHP.

Preparation and characterization of WO3 bonded imidazolium sulfonic acid chloride as a novel and green ionic liquid catalyst for the synthesis of adipic acid
Bhuyan, Bishal,Paul, Bappi,Vadivel, Sethumathavan,Dhar, Siddhartha Sankar
, p. 99044 - 99052 (2016)
A novel nano WO3-bonded imidazolium-sulfonic acid chloride (WO3-IL) was prepared, and characterized by FT-IR, XRD, SEM, TEM, EDX and BET. The as synthesized WO3 nanoparticle supported ionic liquid is studied as a heterogeneous catalyst for the liquid phase oxidation of cyclohexene to adipic acid. Apart from cyclohexene, a few other six-eight membered cyclic alcohols and ketones are converted into their dicarboxylic acids in high yields and in short reaction times employing the same reaction protocol. The synergy between the WO3 and ionic liquid is assumed to play a significant role towards its very high catalytic activity. The recyclability of the catalyst is proved to be noteworthy as the catalyst exhibits no significant change in its catalytic activity even after five cycles of reuse.

Oxidative Cleavage of Vicinal Diols at the Nickel Hydroxide Electrode
Ruholl, Heinrich,Schaefer, Hans J.
, p. 54 - 56 (1988)
Vicinal diols are oxidatively cleaved with good yields by electrolysis at an oxide covered nickel electrode in an aqueous alkaline electrolyte and an undivided cell.The method is applied in the synthesis of optical pure derivatives of 2,2-dimethyl-1,3-dioxolane-4-carboxylic acid.

Preparation method of aliphatic dicarboxylic acid
-
Paragraph 0079-0080, (2021/03/17)
The invention discloses a preparation method for aliphatic dicarboxylic acids. The preparation method mainly employs acetyl carboxylic acids and/or acetyl carboxylates as raw materials for preparing the aliphatic dicarboxylic acids in a high yield through a nonoxidation process. The preparation technology is simple, efficient, short in flow, less in by-product and suitable for large-scale industrialized production, and the obtained aliphatic dicarboxylic acids are high in purity, and are applicable to synthesize polyesters, polyamides, polyurethanes and other engineering plastic and are used as chemical engineering raw materials and medicine intermediates.
Direct and Selective Synthesis of Adipic and Other Dicarboxylic Acids by Palladium-Catalyzed Carbonylation of Allylic Alcohols

supporting information, p. 20394 - 20398 (2020/09/21)
A general and direct synthesis of dicarboxylic acids including industrially important adipic acid by palladium-catalyzed dicarbonylation of allylic alcohol is reported. Specifically, the combination of PdCl2 and a bisphosphine ligand (HeMaRaphos) promotes two different carbonylation reactions with high activity and excellent selectivity.
