What is the chemical structure of 1- (diaminomethylene) -2- (2-phenethyl) guanidine hydrochloride (1:1)?
(1) To clarify the chemical structure of this substance, we must first analyze the groups contained in its name. The groups involved in " (dihydroxyacetyl) " and " (2-naphthyl ethyl) " are both common in organic chemistry.
"Dihydroxyacetyl", according to its name, this group contains an acetyl group structure, and there are two hydroxyl groups attached to it. For acetyl groups, the structure of -CO-CH is also, while the hydroxyl group is -OH. Therefore, the structure of the dihydroxyacetyl group is - CO - CH (OH) 2O. In this structure, the activity of the carbonyl group (- CO -) is quite high, and the hydroxyl group also has a certain reactivity. The coexistence of the two makes the group exhibit unique chemical properties.
"2-naphthyl ethyl", naphthalene is a fused ring aromatic hydrocarbon with a structure of two benzene rings. At position 2 of the naphthalene ring, ethyl (- CH _ 2 - CH _ 3) is connected to form "2-naphthalene ethyl", and its structure is naphthalene ring - 2 - CH _ 3 - CH _ 3. The naphthalene ring is aromatic and chemically stable, but the C-C bond where it is connected to the ethyl group may initiate a reaction under certain conditions.
(2) As for the " (1:1) anhydride", the anhydride is the product obtained by removing a molecule of water from the two-molecule carboxylic acid. Let the anhydride be formed by the loss of water from a dibasic acid, which is connected with "dihydroxyacetyl" at one end and "2-naphthalene ethyl" at the other end.
When a 1:1 anhydride is formed, the characteristic structure of the anhydride must exist in its chemical structure, that is, the two carbonyl groups are connected by oxygen atoms (-CO-O-CO -). On both sides of this structure, one side is a group containing dihydroxyacetyl group, and the other side is a group containing 2-naphthyl ethyl group.
Overall, the chemical structure of the substance is centered on the acid anhydride structure, and there are groups with different characteristics on both sides. Acid anhydride has high activity and is prone to hydrolysis, alcoholysis and other reactions; while the hydroxyl group of "dihydroxyacetyl" can participate in esterification and other reactions, and the naphthalene ring of "2-naphthalene ethyl" can undergo electrophilic substitution and other reactions. This structure endows the substance with rich and diverse chemical properties and may have unique uses in organic synthesis and other fields.
