Cyanamide is the name for a functional group with the formula R 1 R 2 N−C≡N where R 1 and R 2 can be a variety of groups. These compounds are called cyanamides . One example is naphthylcyanamide, C 10 H 7 N(CH 3 )CN, which has been produced by the von Braun reaction , [ 19 ] a general method for the conversion of tertiary amines to ...
CaCN 2 + 2 NaCl + C → 2 NaCN + CaCl 2 Frank and Caro developed this reaction for a large-scale, continuous production process. It was particularly challenging to implement because it requires precise control of high temperatures during the initial igniter step; the melting point of calcium cyanamide is only about 120°C lower than the boiling ...
A CN bond is strongly polarized towards nitrogen (the electronegativities of C and N are 2.55 and 3.04, respectively) and subsequently molecular dipole moments can be high: cyanamide 4.27 D, diazomethane 1.5 D, methyl azide 2.17, pyridine 2.19. For this reason many compounds containing CN bonds are water-soluble.
The core −C(=O)−(N) of amides is called the amide group (specifically, carboxamide group). In the usual nomenclature, one adds the term "amide" to the stem of the parent acid's name. For instance, the amide derived from acetic acid is named acetamide (CH 3 CONH 2 ).
Theanine is an analog of this amino acid, and its primary amide, L-glutamine (also a proteinogenic amino acid). Theanine is a derivative of glutamine that is ethylated on the amide nitrogen (as the name N 5 -ethyl- L -glutamine describes), or alternatively, to the amide formed from ethylamine and L -glutamic acid at its γ- (5-) side chain ...
N-acyl amides are primarily involved in cell-to-cell communication in biological systems. An example of this is the lipid signaling system involving transient receptor potential channels (TRP), which interact with N-acyl amides such as N-arachidonoyl ethanolamide (Anandamide), N-arachidonoyl dopamine and others in an opportunistic fashion.

Structures of three kinds of amides: an organic amide (carboxamide), a sulfonamide, and a phosphoramide. In chemistry, the term amide (/ ˈ æ m aɪ d / or / ˈ æ m ɪ d / or / ˈ eɪ m aɪ d /) [1] [2] [3] is a compound with the functional group R n E(=O) x NR 2, where x is not zero, E is some element, and each R represents an organic group or hydrogen.

The −OH group is replaced by an −NH 2 group and the =O group is replaced by =N R, giving amidines the general structure R n E(=NR)NR 2. [ 10 ] [ 11 ] [ 12 ] When the parent oxoacid is a carboxylic acid , the resulting amidine is a carboxamidine or carboximidamide ( IUPAC name).
