N tertiary

There are also, although not much met with, an aldehyde and a cyanide musk. The former is dinitro-tertiary - butyl-xylyl-aldehyde, Cg(CH3),C(CH3)3(NO,),CHO, melting at 112°, and the latter is diniti n-tertiary-butyl-xylyl-cyanide, Cg(CH3),CN. C(CH3)3(N03), melting at 110°.

The reason for the selective formation of the highly hindered N-tertiary alkyl amine isomer appears to be that the tertiary 7r-allylic carbon is more susceptible to nucleophilic attack by the amine than the secondary carbon, presumably because of the weaker palladium-tertiary carbon bond. Similar results have been observed in several related reactions. 

Although the dithiocyanate (XXVI) is ionic in aqueous ethenolic solution, a later x-ray analysis (1959) showed that in the crystalline state the nickel atom is at the center of an octahedron, being coordinated to the four amino groups of the tetramine and to the nitrogen atoms of the two thiocyanate groups, the interatomic distances being Ni-N(primary) 2.20, Ni-N(tertiary) 2.13, and Ni-N(NCS) 2.06 A.

This report describes mainly C2-C4 CF3-substituted reagents derived from trifluoroacetic acid, trifluoroacetoacetate or from trifluoropropene. Several useful C2 reagents with CF3-substitution were obtained from N-tertiary trifluorothioacetamides as shown in the schemes to be detailed below. We have also elaborated the chemistry of the so far hardly studied trifluoroacetic dithioesters and of several CF3-substituted iminium salts (schemes 5a and 5b). 

Amines - Compounds formally derived from ammonia by replacing one, two, or three hydrogen atoms by hydrocarbyl groups, and having the general structures RNH (primary amines), RjNH (secondary amines), R N (tertiary amines). [5]... 

In the crystal structure of [Cu(Me2NCHjCH2NH2)2] + 2(F3CCO-CH-CO--CF3)- (61) the copper atoms lie on symmetry centres. The Cu-N(primary amine) distance of 1.989(3) A is significantly shorter than the Cu-N(tertiary amine) distance of 2.064(3) A. Only weak interaction between the metal and the anions is suggested by the Cu-O distance of 2.793(2) A. The dimensions of the anions are consistent with complete delocalization of the double bonds. In (Ci4Hi,N )[Cu(F8CCO-CH CO CF3)3)] (62r the double...
