The remarkable activating influence of the dialkylaminoalkyl side-chain was still shown when the harmol nucleus was replaced by other basic nuclei or even by a simple substituted amino-group, and out of an extensive series of compounds of the general formula (D) aK-tetra-n-amyldiamino-M-decane proved to be the most active. 

It has been shown by various workers 3 that the action of alkaloids on protozoa is influenced in a marked degree by the pH of the medium in which the action is exerted, and at a pH of 6-2 to 6-3 aK-tetra-n-amyl-diamino-n-decane proved to be 3 to 5 times as active as emetine, and even in presence of blood at least as active. In view of these promising results of in vitro tests the synthetic product was tried clinically, but proved not to be sufficiently active to be of practical value. This work is being continued and extended by a team of workers led by Goodwin and Sharp, who have published two papers dealing (1) with amines which can be regarded, like Pyman s type A, as diamines derivable from the accepted emetine formula and (2) variants on the bis(diamylamino) decane referred to above.

Mirex is a white, odorless, free-flowing, crystalline, nonflammable, polycyclic compound composed entirely of carbon and chlorine. The empirical formula is C10CI12, and the molecular weight 545.54 (Hyde 1972 Waters et al. 1977 Bell et al. 1978 NAS 1978 Menzie 1978 Kaiser 1978). In the United States, the common chemical name is dodecachlorooctahydro-l,3,4-metheno-2H-cyclobuta[c,(i]pentalene. The systematic name is dodecachloropentacyclo 5.3.0.0 .0 . 0" decane. Mirex was first prepared in 1946, patented in 1955 by Allied Chemical Company, and introduced...

The intramolecular cyclization dominates other possible reactions even in solvents highly susceptible to free radical attack (110). Thus, irradiation of 4,5-octanedione in butanal gives 2-hydroxy-3-methyl-2-propylcyclobutanone in 92% yield (110). Irradiation of 1,2-cyclo-decanedione (Formula 264) gives 1-hydroxybicyclo [6.2.0 ]decan-10-one (Formula 265) in 74% yield and cyclooctanone (Formula 266) in 9% yield (111). The cyclooctanone is produced together with ketene by a secondary photolysis of Formula 265 (111). 

Sulfonic acids and sulfonate salts contain the -S03H and -SO) groups, respectively, attached to a hydrocarbon moiety. The structural formulas of benzene sulfonic acids and of sodium 1 -(p-sulfophenyl)decane, a biodegradable detergent surfactant, are shown in Figure 1.19. The common sulfonic acids are water-soluble strong acids that lose virtually all ionizable H+ in aqueous solution. They are used commercially to hydrolyze fat and oil esters to produce fatty acids and glycerol used in chemical synthesis. 

Relatively simple ruthenium-arene compounds of the general formula [Ru(r 6-arene) Cl2(pta)], (pta = l,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decane), termed RAPTA compounds (see Fig. 2 for some examples) were first reported in 2001 [19]. 

The next six alkanes are named pentane, hexane, heptane, octane, nonane, and decane. Their molecular formulas are C5HI2, C6H14, C7H16, CaHJg, CjH, and C10H22. The alkanes do not stop at the ten-carbon chain however. Since these first ten represent flammable gases and liquids and most of the derivatives of these... 

Isobutane, isopentane, and neopentane are common names or trivial names, meaning historical names arising from common usage. Common names cannot easily describe the larger, more complicated molecules having many isomers, however. The number of isomers for any molecular formula grows rapidly as the number of carbon atoms increases. For example, there are 5 structural isomers of hexane, 18 isomers of octane, and 75 isomers of decane We need a system of nomenclature that enables us to name complicated molecules without having to memorize hundreds of these historical common names. 

Figure 11 The shear viscosity for liquid decane at T = 480 K and P = 170 atm calculated three different ways NEMD-NVT, NEMD-NPX and by means of the Green-Kubo formula (Eqs. [198]). The Green-Kubo value is actually at y = 0 but is placed on the y axis as a guide to the eye. The linear regime is reached when y 0.005 ps". Note the ensemble-dependent results in the shear thinning regime.

You can further condense structural formulas by writing the —CH2— unit in parentheses followed by a subscript to show the number of units, as is done with nonane and decane. 

This ring system has also been referred to as 1,3,8-triazabicyclo-[4.4.0]decane and numbered as shown in formula 15 below. No work has been performed on unsaturated derivatives of this heterocycle, it having attracted attention only as a derivative of piperazine. 

Only saturated derivatives of this heterocycle are known, and they have been named as l-oxa-7,10-diazabicyclo[4.4.0]decanes, numbered as in formula 1. 

The root name decane indicates a ten-carbon chain. There is a methyl group at the number 4 position and an isopropyl group at the number 5 position. The structural formula is... 

In Table 21.2, you can see that -CH2- is a repeating unit in the chain of carbon atoms. Note, for example, that pentane has one more -CH2- unit than butane. You can further condense structural formulas by writing the -CH2- unit in parentheses followed by a subscript to show the number of units, as is done with octane, nonane, and decane.

Spiroannelation. The complete paper on the reaction of the enolates of a-formylcycloalkanones with this reagent to form spiro[4.5]decanes (6, 93 94) has been published. The formulas for /3-vetivone (6) and a-vetispirene (7) in 6,94 should be corrected as shown. 

After Butane, the names of these compounds are from the Greek for the number of carbon atoms followed by the suffix -ane. So, Decane would have the formula... 

They have a different structure, although they both have the same molecular formula. One is called normal butane, abbreviated to -butane the other may be called isobutane or 2-methylpropane - the latter name describes the structure of the compound, as you will see later. These compounds are isomers of one another. They are not the same compounds and have different melting points, boiling points and solubilities. Isomers are compounds which have the same moiecuiar formuia, but different moiecuiar structures. After butane, the longer the carbon chain of an alkane, the more structurai isomers are possible for a particular molecular formula. For example, there are 75 decanes (C10H22) and over three-hundred-thousand eicosanes (C20H42) ...
