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.

METHOD FOR PRODUCING DICARBOXYLIC ACID
-
Paragraph 0115, (2021/05/21)
A method for producing dicarboxylic acid. The method includes: subjecting a raw material system including a cyclic olefin and a lower monocarboxylic acid to an addition reaction in the presence of an addition reaction catalyst to generate an intermediate product system including cyclic carboxylic acid ester; and subjecting the intermediate product system including cyclic carboxylic acid ester to a ring-opening and oxidation reaction in the presence of an oxidant and an oxidation catalyst to generate a corresponding dicarboxylic acid product. The addition reaction in the dicarboxylic acid synthesis route achieves a high single-pass conversion rate, and the selectivity of the corresponding cyclic carboxylic acid ester is high. The addition-oxidation synthesis route achieves faster reaction rates for both the addition reaction and oxidation reaction, and high yield of corresponding dicarboxylic acid product. The addition-oxidation based synthesis route is suitable for continuous, stable and large-scale production of corresponding dicarboxylic acid product.
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.
