Decane decanone

This beneficial effect was attributed to rate enhancements of reduction processes. With benzoic acid, total degradation of the ring to CO2 occurred and the detection of salycilic acid suggested the intervention of 0H° radicals (56). These radicals were also proposed to explain the oxidation of n-Cx alkanes (x = 6,7,9,10) and of cyclohexane in 1 1 vol. water ydrocarbon two-phase mixtures over 10 wt °l Pt/Ti02 Traces of alcohols (and of 2-, 4-, 5-decanone with decane) were detected. No transformation occurred without O2 and in the absence of H2O the rate was substantially decreased. The role of Pt was attributed to a greater ease of oxygen reduction however the oxidation rate was only decreased by a factor of about 1.5 without Pt (59). 

Decane is an alarm pheromone of the ant C. obscuripes866 Decanal (A95) is a pheromone component of larvae of C. pomonella (see Section 4.04.5.3.7),382 and is used by the red bug C. lectularius as an aggregation pheromone component.193 Males of a long-horned beetle, the coffee white stem borer Xylotrechus quadripes, a serious coffee pest in India, produce (S)-2-hydroxy-3-decanone (A96) as sex pheromone to attract female beetles.393 9-Oxo- (A97) and 9-hydroxydecanoic acid (A98) are the major sex pheromone components of females of the scoliid wasp Campsoscolia ciliata. Interestingly, the orchid Ophrys speculum also produces these compounds to attract males of Campsoscolia for pollination.394 ( )-4-Decanolide (A99)... 

In a previous study various processes (oxidation of hydroquinone to benzoquinone, oxidation of 1-decane to 2-decanone and allylic oxydation of cyclohexene) were investigated with the use of Fe(Pc)-Y. Beside the simple separation of phases, the high activity of the encaged Fe(Pc)-Y complex was retained during several catalytic cycles [14]. 

This reaction was reinvestigated with cw-l,7-dimethyltricyclo[4.4.0.0 ]decan-3-one (30) as a model compound. The reduction with lithium to the spiro[4.5]decanone product occurred predominantly with inversion of configuration at the jS-carbon atom. However, the ratio of inversion to retention depends on the reaction temperature and the amount of alcohol added. Both higher temperature and more alcohol increased the proportion of the retention product. 

The influence of alkyl substituents on the direction of cleavage in a series of 1-methyl-tricyclo[4.4.0.0 ]decan-3-ones 39 has been studied. In the absence of an additional substituent, the formation of the brominated spiro[4.5]decanone compound 41 was slightly favored.

In a different approach to the spiro[4,5]decane ring system, Naegeli " has synthesized decanones of the type (228) by way of cationic cyclizations of appropriate a,/8-unsaturated ketones, e.g. (227).
