Konjugierte Enine werden an der C=C-Dreifachbindung durch Bis-[2-methyl-pro-pyl]-aluminiumhydrid in Abhangigkeit von der Struktur hydrometalliert oder metalliert2. 

The number neit to each point corresponds to enines In Table 2 ). 

The above-described hydrotelluration have been successfully applied to conjugated enines and dimes, functionalized alkynes and diines. providing a useful method for the synthesis of organoteUuro 1,3-butadienes, organotelluro 1,3-enines and functionalized vinylic tellurides with the Z configuration at the newly formed C=C bond. 

Sensory. Sensory analysis is one of the oldest accepted methods forjudging seafood quality and freshness. Although fairly accurate, it unfortunately requires trained, experienced panelists to attain accuracy. Perez-Villarreal (( u evaluators experienced in sensory analysis of fish to judge freshness and quality. Results of the study showed sensory scores were better correlated with microbiological analyses, especially total viable counts, than with chemical analyses such as trimethylamine or enine nucleotide decomposition (6). 

I lu flask is surrounded by an ice-calcium chloride cooling nii, lure, and the aluminum chloride is added in small portions bom the Krlenmeyer flask at such a rate that the temperature is niainlaincd between —5° and 0°. After the addition is complete, I lie mi.xiure is. stirred for an additional 30 minutes, and the temperature is then allowed to rise slowly to 10°. The red complex wliidi forms is collected with suction on a sintered-glass funnel and washed thoroughly with dry benzene (Note 2). The complex is added in small portions Iiy means of a spatula with stirring to a 600 ml. beaker nearly filled with a mixture of ice and con-eeidrated hydrochloric acid. I he mixture is then allowed to enine to room temperiitlire, and the crude ketone is collected on a sui t ion filter. 

Before discussing the experimental aspects in more detail a word about the measurement of capture cross sections is in order. At a time slightly greater than tp, just after the initial fast transients [exp( — th ) terms] have died out, the rate of carriers entering the conduction band will be enin, tp), so that...

The Joules brought into the system originate in the chemical energy of methane. We consider 10 J, Enin = 10, and follow the fate of these 10 J with the first and second laws. From process data, it follows that 5J end up in electricity and 4 J in hot water. One Joule finds its way through the chimney. The 5 J of electricity increase the temperature of water of ambient conditions to that of hot water by means of a heat pump based on the efficiency of this heat pump, 10 J are withdrawn from the environment and 15 J of hot water are the result. 

Even though it is commonly referred to as sphingosine, its proper chemical name is D-erythro-1,3-dihydroxy-4, 5-trans-octadecene. Other satisfactory names are rran.v-4-sphingosine, sphing-4-enine, or sphingenine in any event, all the naturally occurring sphingolipids contain only the D-erythro form. 

Amide reduction occurs by nucleophilic addition of hydride ion to the amide carbonyl group, followed by expulsion of the oxygen atom as an slu-eninate anion to- give an iminium ion intermediate. The intermediate iminium ion ia then further reduced by LiAlH to yield the amine.
