- reactions of benzene diazonium salton Aug 5, 2013Replacement reaction of benzene diazonium chloride by cyanide ion Benzene diazonium salt with cuprous cyanides in presence of potassium cyanide gives cyanobenzene (benzene nitrile)Cyanobenzene formed can be converted to benzoic acid by hy...
- Sandmaeyer's Reaction - benzene diazonium saltReplacement reaction of benzene diazonium chloride by halide ion When the solution of freshly prepared benzene diazonium salt is trated with a mixture of cuprous chloride or cuprous bromide in presence of concentrated HCL or HBr, we get chlorobenz...
- Reactions of benzene diazonium chlorideon May 14, 2013 in benzene diazonium chloride Diazonium saltChemical reactions of benzene diazonium chlorideDue to unstable nature diazonium group ( -N2- X+) is a good leaving group. In most of the reactions of diazonium salt, -N2-X+ group is replaced by other groups. Such reactions are usually gr...
- Diazonium salton May 11, 2013 in Diazonium salt organic chemistryDiazonium salt reactionsDiazonium salts have N2 X functional group attached to an aryl group. They are highly unstable and are mainly used as a synthetic intermediate for various compounds. Alkyl diazonium salt do not exist even below 00C. Nomen...
- Cyanides and Isocyanideson Apr 12, 2013 in Cyanide organic chemistryCyanides are the compounds with functional group -CN and can be regarded as the derivatives of hydrogen cyanide (HCN). The cyanide group is an ambident group. This means cyanide group can attach to alkyl or aryl group through both carbon atoms as wel...
- Reaction of Primary Amines with Nitrous Acidson Mar 23, 2013 in organic chemistry AmineReaction of nitrous acid with Aromatic Primary amines At 273 - 278 K, atomic primary amines react with sodium nitrite and dilute HCl, to give aromatic diazonium salts. For example, aniline forms benzene diazonium chloride.Aromatic diazonium salts are...
- Amine Carbonyl Reaction Mechanismon Feb 25, 2013 in organic chemistry AmineReaction of Amine with Carbonyl compundsOnly primary amines react with aldehydes and ketones and condensation products are obtained. These condensation products are known as imines or Schiffs bases.R-CHO (aldehyde) + RNH2 ---------> RCH = N-...
- acylation of amineson Feb 13, 2013 in organic chemistry AmineAcylation of amines mechanismBoth aliphatic and aromatic primary and secondary amines undergo N-acetylation. This acetylation can be effected using acid halides or anhydrides in presence of a base (pyridine) and the product obtained is an amide. Base...
- properties of amineson Jan 30, 2013 in organic chemistry AmineChemical properties of aminesIn most of its reaction, amines act as a nucleophile or a base due to lone pair on nitrogen. In aromatic amines, due to resonance, the -NH2 group make the ring more susceptible to electrophilic substitution at ortho and p...
- Amine Propertieson Jan 21, 2013 in organic chemistry AminePhysical Properties of Amine1. Physical state of AmineLower amines are gases while higher members are mostly liquids. Amines are almost unpleasant, having fishy smell. In the pure state amines are colourless, but in certain case they become colour...
