Benzaldehyde (C 6 H 5 CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is among the simplest aromatic aldehydes and one of the most industrially useful. It is a colorless liquid with a characteristic almond -like odor , and is commonly used in cherry -flavored sodas . [ 5 ]
Sodium borohydride is an odorless white to gray-white microcrystalline powder that often forms lumps. It can be purified by recrystallization from warm (50 °C) diglyme. [10] Sodium borohydride is soluble in protic solvents such as water and lower alcohols. It also reacts with these protic solvents to produce H 2; however, these reactions are ...
Diphenylmethanol may be prepared by a Grignard reaction between phenylmagnesium bromide and benzaldehyde [citation needed]. An alternative method involves reducing benzophenone with sodium borohydride or with zinc dust or with sodium amalgam and water. [3]
In the classic example, benzaldehyde is converted to benzoin (PhCH(OH)C(O)Ph). [3] The benzoin condensation was first reported in 1832 by Justus von Liebig and Friedrich Wöhler during their research on bitter almond oil. [4] The catalytic version of the reaction involving cyanide was developed by Nikolay Zinin in the late 1830s. [5] [6 ...
In the lab, phenyl-2-nitropropene is produced by the reaction of benzaldehyde and nitroethane in the presence of a basic catalyst like n-butylamine.The reaction is a nitroaldol reaction, and is a variant of a Knoevenagel condensation reaction, which is one of a broader class of reactions called Henry condensations, or simply Henry reactions.
4‑Hydroxybenzaldehyde (para‑hydroxybenzaldehyde) is an organic compound with the formula C 6 H 4 OH(CHO). [ 4 ] [ 5 ] Along with 2-hydroxybenzaldehyde and 3-hydroxybenzaldehyde , it is one of the three isomers of hydroxybenzaldehyde .
4-Nitrobenzaldehyde is an organic compound with the formula O 2 NC 6 H 4 CHO.It is one of three isomers of nitrobenzaldehyde. It contains a nitro group para-substituted to an aldehyde.
The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines. The reaction is an example of reductive amination. [1] The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent. It requires high temperatures, usually between 120 and 130 °C; for the ...
