There remain three Bronsted acids that have no liquid phase enthalpy of formation data that we know of dodecanethiol, cyclohexyl methyl amine and A-methyl dodecanamide. Although the enthalpy of formation of 1-dodecanethiol has not been measured, there are experimental values available for other members of its homologous series, C2-C7, Cjo. From a weighted least-squares analysis of the data from which a slope, —25.4, and an intercept, —23.3, are derived, the enthalpy of formation of dodecanethiol is —328.1 kJ moH The enthalpy of formation of dodecanethiolate magnesium bromide is thus estimated as —744.6 kJmoH. We can estimate the enthalpy of formation of cyclohexyl methyl amine by assuming equation 12 is thermoneutral. 

From the archival enthalpies of formation of the other species, the enthalpy of formation of cyclohexyl methyl amine is —145.4 kJmoH. From equation 11, the enthalpy of formation of the corresponding salt is —501.2 kJmoH. Attempts to estimate an enthalpy of formation for A-methyldodecanamide reveals a paucity of data to work with, primarily for unsubstituted and A-methylamides . There is much enthalpy of formation data for w-alkyl carboxylic acids, including dodecanoic acid. The methylene increment... 

Man erhalt auf diese Weise z.B. aus Triethylamin-oxid und 1-Brom-octan bzw. Brom-essigsaure-ethylester als Elektrophil 1-Diethylamino-octan (51%) bzw. Diethylamino-essigsaure-ethylester (31%) und aus l-Methyl-piperidin-1-oxid und 1-Brom-octan bzw. Bromessigsaure-ethylester 1-Octyl-piperidin (47%) bzw. Piperidinoessigsaure-ethylester (38%). Nach dem zweiten Reaktionsweg erhalt man z. B. aus Cyclohexyl-dimethyl-amin-oxid mit Cyan-trimethyl-silan als Nukleophil (Cyclohexyl-methyl-amino)-acetonitril (71%). 

Alkyl aryl ketimines were reduced with up to 99% ee (Scheme 8) [24]. The high enantioselectivity was not affected by the E Z ratio of the imines. For example, a 1.8 1 E Z mixture of the N-propylimine of 4 -methoxy-3-methyIbuty-rophenone was converted to the desired product in 97% optical yield. Hydrosilylation of the N-propylimine of cyclohexyl methyl ketone with a substrate to Ti molar ratio of 2,000 1 was completed to give the product in 98% ee [24]. N-Benzylimine of 2-octanone, a simple aliphatic ketimine, was reduced with 69% optical yield. The reduction of W-benzyl-l-indanimine gave the corresponding amine in 92% ee (Scheme 9) [24]. 

Asymmetric reduction of ketones.1 Lithium aluminum hydride, after partial decomposition with 1 equiv. of 1 and an amine additive such as N-benzylmethylamine, can effect asymmetric reduction of prochiral ketones at temperatures of — 20°. The highest selectivity is observed with aryl alkyl ketones (55-87% ee), but dialkyl ketones can be reduced stereoselectively if the two groups are sterically different. Thus cyclohexyl methyl ketone can be reduced with 71% ee.

Other alkylamines can be made in similar fashion from the alcohol and ammonia (Fig. 4). Methyl, ethyl, isopropyl, cyclohexyl, and combination amines have comparatively small markets and are usually made by reacting the correct alcohol with anhydrous ammonia in the vapor phase. 

Hydrogenations of nitrobenzene and p-nitrotoluene over supported noble metal catalysts are often investigated as model reactions, as they consist of various elemental reactions with different intermediates that can react with each other as depicted in the scheme below for p-nitrotoluene [321], At short reaction times, the intermediates are predominantly formed, whereas complete conversion to p-methyl aniline is achieved at long reaction times. Aniline itself can react further to form side products such as cyclohexanol, cyclohexyl amine and other species.

These principles were used to assign Cls, Ols and Nls NEXAFS spectra of polymers important to the microelectronics industry. Interpretation of polyamic acid and polyimide spectra were aided by assigning the spectra of simpler polymers and monomers. The compounds studied in the form of spun films were poly(vinyl methyl ketone) (PVMK), poly(dimethyl phenylene oxide) (PMPO), poly(pyromellitimido 4,4-methylene bis-cyclohexyl amine) (PMDA-MBCA PI), and poly(pyromellitimido oxydianiline) (PMDA-ODA PI) and in the form of MBE-deposited films were poly(amic acid) (PAA), and PMDA-ODA PI. Changes in the NEXAFS spectra as a function of evaporated Cr overlayer thickness were measured for PVMK, PMPO and PMDA-ODA PI. Evolution of the NEXAFS spectra as a function of deposited organic film thickness and thermal treatment were measured for PAA on Cu and Cr substrates.
