Cobalt(II) complex 1a-f derived from Schiff bases act as efficient catalysts during the oxidation of wide range of organic substrates(e.g. alkenes, alcohols, benzylic compounds and aliphatic hydrocarbons) with dioxygen in the presence of aliphatic aldehydes or ketones or ketoesters. EPR studies on 1a-f complexes suggest that the aliphatic carbonyl compounds promote the formation of a cobalt(II)-superoxo species responsible for the oxidation of organic compounds. These studies also demonstrate the role of ligands on cobalt in controlling the chemoselectivity of these oxidations. A plausible mechanistic rational is also provided for these oxidations.
Cobalt catalyzed oxidation of cyclic alkenes with molecular oxygen: Allylic oxidation versus double bond attack

Cobalt (II) Schiff's base complex 1 and 2 exhibit a remarkable chemoselectivity during oxidation of cyclic alkenes with molecular oxygen in the presence of 2-methylpropanal. Catalyst 1 encourages the oxidation of double bond to give epoxide as the major product whereas catalyst 2 promotes mainly the allylic oxidation leading to allylic alcohols or enones.

, (2008/06/13)
A traction drive fluid composition comprising a hydrocarbon having a bicyclo octane skeleton, such as a bicyclo(3,2,1) octane skeleton, a bicyclo(2,2,2)octane skeleton or a bicyclo(3,3,0)octane skeleton. The traction drive fluid has a low viscosity and has a high traction coefficient over a wide temperature range.
A Simple One-pot Method for Conversion of Terminal Alkenes into Carboxylic Acids via Hydroboration

, p. 844 - 846 (2007/10/02)
Hydroboration of terminal alkenes with NaBH4/CH3COOH followed by oxidation with aqueous chromic acids in the presence of t-butanol gives the corresponding carboxylic acids in moderate to good yields (50-75percent).

, p. 1190 - 1196 (2007/10/02)
Oxiranes derived from some alkenes, with olefinic bonds present in different stereoelectronic environments, have been treated with Cr(VI)-reagents.The major products obtained have been identified and their formation rationalized.In some cases, the method becomes synthetically useful for C-C bond cleavage.
