Diazomethane is the simplest diazo compound, consisting of a methylene carbon (CH2) bonded to dinitrogen (N2 ). Just for fun, before we go any further, see if you can draw a proper Lewis structure for diazomethane, CH2N2. Note the two important resonance forms of diazomethane. The key resonance form for our … See more Well, carboxylic acids can be made into methyl esters by treating them with the reagent diazomethane, CH2N2. This is a very mild way of converting carboxylic acids into esters. Due to the aforementioned … See more The conversion of carboxylic acids to methyl estersis a two-step process. In the first step, diazomethane, a weak base, is protonated on carbon to give H3C-N2(+). This is an example of … See more One final application of diazomethane in introductory organic chemistry is as a source of carbenes. Carbenes are divalent carbon atoms (i.e. bonded to two atoms) and possess twonon … See more There are three main phases in the Arndt-Eistert synthesis. The first is reaction of diazomethane with the acid halide to give a new species known as a diazoketone. 1. Acid halides readily … See more WebDiazomethane methylates carboxylic acids because carboxylic acids readily protonate it, giving an extremely unstable diazonium cation. This compound is desperate to lose N 2 and so it does with the N 2 being substituted by the carboxylate anion. The carboxylate anion is in exactly the right position to carry out an S N 2 reaction as shown above.
