Oxidative dehydrogenation of vicinal diols of bornane and pinane type with chlorine dioxide in dimethylformamide has yielded α-hydroxyketones with high selectivity. 3α-Hydroxy-10β-pinane-4-one has been prepared for the first time with yield of 63-65%; the
Synthesis of 1,11,11-trimethyl-3,6-diazotricyclo [6.2.1.0 2,7]undeca-2,6-diene and 1,15,15-trimethyl-3,10-diazotetracyclo[10.2. 1.02,11.04,9]pentadeca-2,4(9),5,7,10-pentaene from camphoroquinone enantiomers

Optically active camphordihydro-2,3-pyrazine and camphorquinoxaline were prepared from camphoroquinone enantiomers. It was shown that (1S,4R)-(+)-camphoroquinone was formed by oxidation of (1S,3R, 4R)-(-)-3-bromocamphor and (1R,4S)-(-)-camphoroquinone from (1R,3S, 4S)-(+)-3-bromocamphor, respectively. Camphor anhydride was a side product (6-10%) of the reaction. Springer Science+Business Media, Inc. 2007.

A convenient and general method for the synthesis of symmetrical carboxylic acid anhydrides using sodium carbonate/thionyl chloride is described. Copyright Taylor & Francis Group, LLC.
A Cheap, Simple and Efficient Method for the Preparation of Symmetrical Carboxylic Acid Anhydrides
Kazemi, Foad,Sharghi, Hashem,Nasseri, Mohammad Ali
, p. 205 - 207 (2007/10/03)
A manipulatively simple and facile one-pot procedure for the synthesis of symmetrical anhydride is reported. Treatment of carboxylic acids with tosyl chloride in K2CO3 media under solvent free conditions gives the corresponding anhydrides in good to excellent yields in a short reaction time via carboxylic sulfonic anhydride as the key intermediate.
Synthesis of crotonoyl, cynamoyl and p-methoxycynamoyl derivatives of camphoric imide. Crystal and molecular structure of (1R,5S)-3-[(E)-2′-butenoyl]-1,8,8-trimethyl-3-azabicyclo [3.2.1] octane-2,4-dione

, p. 477 - 482 (2007/10/03)
Three derivatives of camphoric acid imide (crotonoyl, cynamoyl and p-methoxycynamoyl) have been synthesized. Crystal and molecular structure of (1R,5S)-3-[(E)-2′-butenoyl]-1,8,8-trimethyl-3-azabicyclo[3.2.1]octane-2,4- dione has been determined by X-ray diffraction technique. Crystal data for C14H19NO3: orthorhombic, P212121, a = 10.555 (2) A, b = 11.406 (2) A, c = 11.632 (2) A, Z = 4, R = 0.051 for 4278 reflections. Despite of a small number of heavy atoms, the absolute structure determination occurred to be successful.
Clay catalysis: A convenient and rapid formation of anhydride from carboxylic acid and isopropenyl acetate under microwave irradiation
Villemin,Labiad,Loupy

The Montmorillonite KSF catalyses the synthesis of anhydrides from carboxylic acids in the presence of isopropenyl acetate under microwave irradiations.
PHOTOSENSITIZED OXYGENATION OF 3-DIAZOCAMPHOR
Okada, Keiji,Mukai, Toshio
, p. 359 - 360 (2007/10/02)
Photosensitized oxygenation of 3-diazocamphor gave camphorquinone and camphoric anhydride in benzene.The yield of camphoric anhydride did not depend on the concentration of added camphorquinone or of diazocamphor.When the reaction was carried out in acetonitrile or benzonitrile, amide 7 or 8 was produced.The formation of amide strongly supports the intermediacy of carbonyl oxide.
