The influence of a 2-pyridinyl substituent on the catalytic performance of aryl iodides as catalyst in iodine(III) chemistry was explored. An efficient Lewis base adduct between the pyridine nitrogen and the electrophilic iodine(III) center was identified and confirmed by X-ray analysis. This arrangement was shown to generate a kinetically competent superior catalyst structure for the catalytic dioxygenation of alkenes. It introduces the concept of Lewis base adduct formation as a kinetic factor in iodine(I/III) catalysis. (Figure presented.).
Cobalt-Catalyzed Oxidations in Volumetrically Expanded Liquids by Compressed Gases

Oxidations of hydrocarbons, cycloalkanes and alkenes, arylalkanes, and a variety of other organic substrates are accomplished by cobalt-N-hydroxysuccinimide co-catalyzed reactions with dioxygen under unusually mild, near ambient conditions of temperature and pressure. The improved safety of the oxidation method and the high yields of product obtained make use of a unique combination of cobalt (II) complexes with N-hydroxysuccinimide. These autoxidation reactions do not have prolonged initiation times. Many of these reactions can be safely performed under normal chemical laboratory conditions and do not require specialized equipment or reagents.

Acid-catalyzed reaction of ethyl 3,6,6-triaryl-3-hydroxy-1,2-dioxane-4- carboxylates yielded ethyl 2,5-diarylfuran-3-carboxylates in 18-40% yield. The reaction of methyl 4-hydroxy-2,3-dioxabicyclo[n.4.0]alkane-5-carboxylates gave methyl 5-aryl-4-(ω-hydroxyalkyl)-2-methylfuran-3-carboxylates in 59- 71% yields.
