Ethyl cyanide

Although in the dry state carbon tetrachloride may be stored indefinitely in contact with some metal surfaces, its decomposition upon contact with water or on heating in air makes it desirable, if not always necessary, to add a smaH quantity of stabHizer to the commercial product. A number of compounds have been claimed to be effective stabHizers for carbon tetrachloride, eg, alkyl cyanamides such as diethyl cyanamide (39), 0.34—1% diphenylamine (40), ethyl acetate to protect copper (41), up to 1% ethyl cyanide (42), fatty acid derivatives to protect aluminum (43), hexamethylenetetramine (44), resins and amines (45), thiocarbamide (46), and a ureide, ie, guanidine (47).

Nitriles are organic derivatives of hydrocyanic acid in which the substituting group is attached to carbon. Their formula is R.C N. Because most nitriles can be derived from corresponding acid amides, R.CO.NH2, by removal of w, they are called nitriles. For instance, the compd CH3.CN is called acetonitrile because it is derived from acetamide. It can also be called methyl cyanide. The compd C2HS.CN is called either propionitrile or ethyl cyanide, etc The first nitrile to be prepared was propionitrile which J. Pelouze obtained in 1834 by distg Ba ethyl sulfate with K cyanide... 

The basic steps are well known after oxidative addition of HCN, we find coordination of ethene, migratory insertion of ethene into the nickel hydride bond, and reductive elimination of ethyl cyanide (propanenitrile). More detailed studies by Du Pont s McKinney and Roe [3] have shown that the productive cycle involves the reductive elimination by the process shown in Figure 11.2.

Olefins react with benzenetellurinyl trifluoroacetate in acetonitrile in the presense of boron trifluoride etherate to give 2-acetaminoalkyl phenyl tellurium oxides that are converted, upon treatment with triethylamine in tetrahydrofuran at 30° for 4 h, to 4,5-dihydro-l,3-oxazoles4. These highly regio- and stereoselective reactions allow the one-pot, high-yield conversion of olefins to 1,3-oxazoles. Ethyl cyanide and phenyl cyanide can be used instead of acetonitrile.
