N-Propyl cyanide

Base-catalyzed trimerizations are facile also for example, trifluoromethyl cyanide trimer-izes in the presence of ammonia, presumably through the formation of the amidine intermediate (139 Scheme 77) (67JOC231). Similarly, perfluoro-n-propyl cyanide forms the 1,3,5-triazine in the presence of sodium methoxide, probably via the imidate (140 Scheme 78) (52JA5633).

This reaction should be done in a well-ventilated hood, t The decaborane is purified by sublimation at 60° and lO" mm. t The n-propyl isocyanide is prepared by the method of Jackson and McKusick/ using 490 g. (2.S mole) of n-propyl iodide and 454 g. (3.3 mole) of silver cyanide. It is observed that, after a long induction period, the reaction becomes quite violent. It is suggested that one half of the propyl iodide be added initially and the other half be added drop by drop over a 2-hour period. The drj- product is used without the final fractional distillation indicated in the reference.

Polymeric complexes are formed when copper(I) cyanide reacts with ammonia or alkyl and aryl isocyanides. The ammine complex consists of Cu-C-N-Cu-C helices linked by metal-metal bonds to form sheets. The NH3 ligands bond normal to the copper atoms and interlock with NH3 protrusions of other sheets (94). Complex CuCN(Bu"NC) is polymeric (272), and the ethyl, propyl, and 2-butyl isocyanide complexes are also known (139). 

Several approaches to the synthesis of the tetrahydrobenzazepine ring system have been described, and excellent methods exist for the preparation of aryl substituted tetrahydrobenzazepines. However, benzazepines that are either unsubstituted or alkyl-substituted on the azepine ring are much less readily obtainable. For instance, the benzazepinone, synthesized by this procedure, was originally isolated, in tow yield, from the mixture of photoproducts obtained from the irradiation of N-[3-(3,4-dimethoxyphenyl)]propyl chloroacetamide. Preparative approaches to the benzazepinones have required multiple steps starting from an N-phenylethylacetamide and involving chloromethylation, cyanide displacement, nitrile solvolysis, hydrolysis to the amino acid and cyclization.7 The f-alkyl derivatives are...
