It is supposed that the nickel enolate intermediate 157 reacts with electrophiles rather than with protons. The successful use of trimethylsilyl-sub-stituted amines (Scheme 57) permits a new carbon-carbon bond to be formed between 157 and electrophiles such as benzaldehyde and ethyl acrylate. The adduct 158 is obtained stereoselectively only by mixing nickel tetracarbonyl, the gem-dibromocyclopropane 150, dimethyl (trimethylsilyl) amine, and an electrophile [82]. gem-Functionalization on a cyclopropane ring carbon atom is attained in this four-component coupling reaction. Phenyl trimethyl silylsulfide serves as an excellent nucleophile to yield the thiol ester, which is in sharp contrast to the formation of a complicated product mixture starting from thiols instead of the silylsulfide [81]. (Scheme 58)... 

According to the latter approach, reducing sugars 128 were reacted with triethylammonium dimethyl boranophosphate in the presence of bis(2-oxo-3-oxazolidinyl)phosphinic chloride as condensing reagent, 3-nitro- 1,2,4-triazole as nucleophilic catalyst and A,A-diisopropyl-A-ethyl-amine to provide boranophosphate triester derivatives 129 as anomeric... 

As a first step toward a dopamine-jS-hydroxylase mimic, basket-shaped receptor 17 was functionalized with two sets of bis-[2-(3,5-dimethyl-l-pyra-zolyl)ethyl]amine ligands to give compound 35 (see Scheme 5). Reaction of 35 with Cu(C104,)2-6H20 yielded complex 36 which was fully characterized [39], Ligand system 35 binds dopamine derivative 37 and phloroglucinol (1,3,5-trihydroxybenzene) with association constants of = 60 and 3500 respectively. The affinity of the Cu(I) analogon of 36 for 37 was very similar to that of 36 itself and amounted to Ka = 60 M L Resorcinol is bound in the cavity of the Cu(I) complex with a Xj-value of 2(XX) M". ...

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). 

Moreover, the formation of enoxy-silanes via silylation of ketones127 by means of N-methyl-N-TMS-acetamide (1 72) in presence of sodium trimethylsilanolate (173) was reported in 1969 and since then, the use of silylating reagents in presence of a catalyst has found wide appreciation and growing utilization as shown in recent papers128-132 (Scheme 27). Diacetyl (181) can be converted by trifluoromethylsul-fonic acid-TMS-ester (182) into 2,3-bis(trimethylsiloxy)-l, 3-butadiene (7treatment with ethyl TMS acetate (7 5)/tetrakis(n-butyl)amine fluoride l-trimethylsiloxy-2-methyl-styrene (i<56)130. Cyclohexanone reacts with the combination dimethyl-TMS-amine (18 7)/p-toluenesulfonic acid to 1-trimethylsiloxy-l-cyclohexene (iSS)131. Similarly, acetylacetone plus phenyl-triethylsilyl-sulfide (189) afford 2-triethylsiloxy-2-pentene-4-one (790)132. ... 

Chlorophenyl) ethyl]amine-2-14 C (407) has been obtained by reduction of 405 with LAH-AICI3620. [2-[p- ( Trifluoromethyl)phenyl]ethyl]amine-2-14C(408) has been obtained similarly from 406. [2-[p-(Trifluoromethyl)phenyl]ethyl]amine-1-14C (409) has been obtained by reduction of 2-[/7-(trifluoromethyl)phenyl]ethanenitrile-l-14C by the same method. N,N-Dimethyl-N-[2-(p-chlorophenyl) ethyl]amine-2-14C has been obtained by reductive amination of 407621.

POCI3 chlorinations (Eq. (8)) are acid-catalyzed reactions of such reaction products]. The hydrogen bonding of azinones is related to that of iV-oxides, discussed below, and to that of ketones (with water and alcohols) and has been demonstrated by infrared measurements on pjn-idinethione in alcohols and by the electronic absorption spectra of azinones in water. 6-Chloro-l,3-dimethyl-pyrimidine-2,4-dione is rapidly aminated at 20° (with heat evolution) by methyl- or ethyl-amines, etc., in protic media (water or alcohols).

A) Solubility. Methyl and ethyl amines are very soluble in water. Try the solubility of the three butylamines, of aniline, and of methyl and dimethyl aniline, by adding a drop to 2 ml of water. Save the solution for the next test. 

Methyl, dimethyl, trimethyl, and ethyl amines are gases under standard conditions. Most common alkyl amines are liquids, and high molecular weight amines are, quite naturally, solids at standard temperatures. Additionally, gaseous amines possess a characteristic ammonia smell, while liquid amines have a distinctive fishy smell.
