Cobalt(II) complex 1a-f derived from Schiff bases act as efficient catalysts during the oxidation of wide range of organicsubstrates(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(III)-superoxo

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.
An acidic and somewhat resinous odor note tending to cistus and olibanium is imparted to a perfume composition or product containing the same by adding the 3,3-dimethylbicyclo-(2,2,1)-heptane-2-carboxylic acid compound thereto.
