AMINES. An amine is a derivative of NH3 in which there is a replacement for one or more of the H atoms of Nil, by an alkyl group, such as -CH3 (methyl) or -C2H5 (ethyl) or by an aryl group, such as (>, H (phenyl) or i ll (naphthyl). Mixed amines contain at least one alkyl and one aryl group as exemplified by methylphenylamine CH3 Nnij O.H . When one, two, and three H atoms arc thus replaced, the resulting amines ate known as primary, secondary, and tertiary, icspectively. Thus, methylamine, CH3NH2, is a primary amine dimethylamine, iCHj) NH, is a secondary amine and trimethylamine. (CHs N. is a tertiary amine. Secondary amines sometimes are called imines tertiary amines, nitriles. 

A new and easy access to the enantiomerically pure rigid bidentate ligand, (-)-[5-(dipheny-larsino)-2,3-dimethyl-7-phenyl-7(5)-phosphabicyclo[2.2.1]hept-2-ene is established via an asymmetric cycloaddition between diphenylvinylarsine and 1-phenyl-3,4-dimethylphosphole using chiral organopalladium(II) complex containing ort/io-metalated dimethyl[l-(2-naphthyl)ethyl]amine as the reaction promoter [61] (Eq. 8A.37). 

The cyclopalladated complex (naphthyl)ethylamine-6, iV]-dipalladium has been used as a chiral template to promote the intramolecular [4 -h 2] Diels-Alder reaction between diphenyl-vinylphosphine and 1-phenyl-3,4-dimethylphosphole. Halide-bridged palladium(ii) dimers of orthopalladated (S)-(-h)-7V,7V-dimethyl-Q -methylbenzylamine and (naphthyl)ethyl]amine were reported by the same authors.Solution and solid-state structures were determined as well as reactions with 3,4-dimethyl-1-phenylphosphole and allyldiphenylphosphine carried out.

In an acetone extract from a neoprene/SBR hose compound, Lattimer et al. [92] distinguished dioctylph-thalate (m/z 390), di(r-octyl)diphenylamine (m/z 393), 1,3,5-tris(3,5-di-f-butyl-4-hydroxybenzyl)-isocyanurate m/z 783), hydrocarbon oil and a paraffin wax (numerous molecular ions in the m/z range of 200-500) by means of FD-MS. Since cross-linked rubbers are insoluble, more complex extraction procedures must be carried out (Chapter 2). The method of Dinsmore and Smith [257], or a modification thereof, is normally used. Mass spectrometry (and other analytical techniques) is then used to characterise the various rubber fractions. The mass-spectral identification of numerous antioxidants (hindered phenols and aromatic amines, e.g. phenyl-/ -naphthyl-amine, 6-dodecyl-2,2,4-trimethyl-l,2-dihydroquinoline, butylated bisphenol-A, HPPD, poly-TMDQ, di-(t-octyl)diphenylamine) in rubber extracts by means of direct probe EI-MS with programmed heating, has been reported [252]. The main problem reported consisted of the numerous ions arising from hydrocarbon oil in the recipe. In older work, mass spectrometry has been used to qualitatively identify volatile AOs in sheet samples of SBR and rubber-type vulcanisates after extraction of the polymer with acetone [51,246].

Aryl alcohol oxidase from the ligninolytic fungus Pleurotus eryngii had a strong preference for benzylic and allylic alcohols, showing activity on phenyl-substituted benzyl, cinnamyl, naphthyl and 2,4-hexadien-l-ol [103,104]. Another aryl alcohol oxidase, vanillyl alcohol oxidase (VAO) from the ascomycete Penicillium simplicissimum catalyzed the oxidation of vanillyl alcohol and the demethylation of 4-(methoxymethyl)phenol to vanillin and 4-hydro-xybenzaldehyde. In addition, VAO also catalyzed deamination of vanillyl amine to vanillin, and hydroxylation and dehydrogenation of 4-alkylphenols. For the oxidation of 4-alkylphenol, the ratio between the alcohol and alkene product depended on the length and bulkiness of the alkyl side-chain [105,106]. 4-Ethylphenol and 4-propylphenol, were mainly converted to (R)-l-(4 -hydroxyphenyl) alcohols, whereas medium-chain 4-alkylphenols such as 4-butylphenol were converted to l-(4 -hydroxyphenyl)alkenes. 

The most successful modifier is cinchonidine and its enantiomer cinchonine, but some work in expanding the repertoire of substrate/modifier/catalyst combinations has been reported (S)-(-)-l-(l-naphthyl)ethylamine or (//)-1 -(I -naphth T)eth Tamine for Pt/alumina [108,231], derivatives of cinchona alkaloid such as 10,11-dihydrocinchonidine [36,71], 2-phenyl-9-deoxy-10, 11-dihydrocinchonidine [55], and O-methyl-cinchonidine for Pt/alumina [133], ephedrine for Pd/alumina [107], (-)-dihydroapovincaminic acid ethyl ester (-)-DHVIN for Pd/TiOz [122], (-)-dihydrovinpocetine for Pt/alumina [42], chiral amines such as 1 -(1 -naphtln I)-2-(I -pyrro 1 idiny 1) ethanol, l-(9-anthracenyl)-2-(l-pyrrolidinyl)ethanol, l-(9-triptycenyl)-2-(l-pyrrol idi nyl)cthanol, (Z )-2-(l-pyrrolidinyl)-l-(l-naphthyl)ethanol for Pt/alumina [37,116], D- and L-histidine and methyl esters of d- and L-tryptophan for Pt/alumina [35], morphine alkaloids [113],...

Optica] resolution of these and related carboxylic acids were achieved using salt formation with alkaloids (strychnine, brucine, cinchonidine) 33,39,44 or with optically active amines [1-phenyl- or l-( 3-naphthyl)ethylamine]4o,44).

Both bis and tris ethylenediamine complexes have been described 12 the latter have been formulated [Sc(en)3]X3 (X=C1 or Br), this being supported by IR data. Heating in vacuum leads to formation of c -[ScX2(en)2]X. A number of complexes qf ScCl3 with primary and secondary amines, mainly aliphatic, have been prepared and their thermochemistry and IR spectroscopy studied.13-15 The compounds are ScCl3 (RR NH), where n = 1-4 and R = R = Me, Et, Pr, Bu or Pe or R = H and R1 - Et, Pr, Bu, Pe, phenyl, benzyl or 2-naphthyl. Further investigation would be necessary to establish the structural nature of these complexes. 

Rubber antioxidants are commonly of an aromatic amine type, such as dibeta-naphthyl-para-phenylenediamine and phenyl-beta-naphthylamine. Usually, only a small fraction of a percent affords adequate protection. Some antioxidants arc substitute phenolic compounds (butylatcd hydro -vamsole, di-tert-butyl-para-cresol, and propyl gallate).

Carbonylation of the 3-phenylallyl acetate 258 under somewhat severe conditions in the presence of tertiary amine and acetic anhydride affords the naphthyl acetate derivative 260. This interesting cyclocarbonylation is explained by the Friedel-Crafts-type cyclization of the acylpalladium 259 as an intermediate [118,119]. Even 5-phenyl-2,4-pentadienyl acetate (261) is cyclocarbonylated to afford 2-phenylphenyl acetate (262) [120],...
