When the temperature is raised, the decyl radicals react with pentyl radicals yielding pentadecane by combination (Reaction 11), decanes, decenes, pentenes, and pentane by disproportionation (15, 16). 

Cp2Zr(H)(Cl) (8). The apparent record for catalyzed double bond movement is on 9-decene-l-ol to decanal (nine positions) using Fe3(CO)i2 (9). However, 30 mol % was required, which means that nearly a mole of metal was used per mole of alkenol. Herein we expand upon our initial report (10) of a very active catalyst (1) which has been shown to move a double bond over 30 positions. Catalyst 1 appears to have an intriguing and useful mode of action, in which the pendant base ligand performs proton transfer on coordinated alkene and Ti-allyl intermediates in a stereoselective fashion. 

With the RCH/RP process, it is possible to hydroformylate propene up to pentenes with satisfying space time yields. On the other hand, heavier aldehydes such as Cio (iso-decanal) or higher from the hydroformylation of nonene(s), decenes, etc. can not be separated from the oxo catalysts by conventional means such as distillation due to thermal instability at the required temperatures and thus especially needs the careful aqueous-biphasic separation technique. There are numerous attempts to overcome the problem of low reactivity of higher alkenes which is due to low miscibility of the alkenes in water [26,27b, 50a,58d]. These proposals can briefly be summarized as ... 

Ehnholt et al.8 produced a broad paper covering raw materials, and in-process and final-product measurements. While the uses are primarily in the food industry, the rancidity was often caused by microorganisms. One case involved off-flavor materials being produced in drying and curing ovens. Marker compounds (concomitant) released during the breakdown process (of saturated and unsaturated compounds) were nonenal, decenal, and octenone for the unsaturated aldehydes and ketones, and nonanal, decanal, and octanone for the saturated molecules. A 10-m folded path gas cell was used with an FT-IR for measurements down to 1 Lig/m3. 

When the suffixes a7nea.nd -eneshow up in a compound name like decane or decene they are usually consistent with the alkane and alkene definitions, but not always. Benzene is a cyclic aromatic hydrocarbon, not a straight chain molecule naphthenes are cyclic compounds. 

The concept of site isolation is important in catalysis. On metal particles one usually assumes that ensembles of metal atoms are necessary to activate bonds and to accommodate the fragments of molecules that tend to dissociate or to recombine. We present here three examples of such effects the dehydrogenation of decane into 1-decene, the dehydrogenation of isobutane into isobutene and the hydrogenolysis of acids or esters into aldehydes and alcohols. In most cases the effect of tin, present as a surface alloy, wiU be to dilute the active sites, reducing thereby the yield of competitive reactions. 

In regard to unsaturation, on flax especially, a marked toxicity of cyclohexene, as compared to cyclohexane, was observed (I). Leonard and Harris (2) investigated this further and noted that while hexene differed little from hexane, both being relatively nontoxic, higher members of the series, even decene, produced severe burn or death in two sprayings, while with n-decane such severe damage was not noted unless five treatments or sprayings were made. This result was much more noticeable on cotton than on soybeans. 

On heating above 200 °C, 2,5-bis(trimethylsiloxy)tricyclo[4.4.0.02 5]decan-7-ones undergo a [2 4- 2] cycloreversion to form either 1,2-divinylcyclohexanes or 1,5-bis(trimethylsiloxy)cyclodeca-1,5-dienes. These are not stable at elevated temperatures and rearrange. After aqueous acidic workup, bicyclo[5.3.0]decene-2,5-diones 13 are isolated.45... 

Reduction of 1-decene had to be carried out at a lower concentration (0.073M) since decene was not completely soluble at the concentrations used in the case of tetralin (0.22M). Electrolysis was interrupted after 0.0062 Faradays were passed through the solution, corresponding to 42.2% conversion of 1-decene to decane at 100% current efficiency. In these runs, a carbon cathode was used. Current efficiency for reducing 1-decene was 27.3%. In the presence of an equimolar amount of terf-butyl alcohol (0.073M), the current efficiency for 1-decene was 38.6%, corresponding to a 41% increase.

Autoxidation of oleic acid leads to the 4 main hydroperoxy-octadecenoic acids 8-HPOE, 9-HPOE, lO-HPOE and 11-HPOE (cf. Fig. 3.28). Fission generates a multitude of volatiles. Octanal (30), nonanal (31), decanal (32), 2( )-decenal (33) and 2( )-undecenal (34) belong to the odour-active ones. 

These terpene notes are supported by (Z)-3-hexenol, (E)-2-hexenal, (E)-2-hexenol with their fresh, green character. Gamma- and delta-lactones (4-decanolide, 5-decan-olide, 4-dodecanolide, 5-dodecanolide-(Z)-7-decen-5-olide) impart the sweet, creamy, buttery, peach and apricot character. 2,5-Dimethyl-4-hydroxy-furan-3(2H)-one and 2,5-dimethyl-4-methoxy-furan-3(2H)-one are responsible for the sweet creamy fruity body. A bouquet of esters imparts the overall fruity character (mainly esters of ethyl-, (Z)-3-hexenyl and butyl alcohol with acetic-, butanoic-, 2-butenoic, 3-hydroxybutanoic- and hexanoic acid).
