Diazomethane esterification mechanism
WebNucleophilic acyl substitution describes a class of substitution reactions involving nucleophiles and acyl compounds. In this type of reaction, a nucleophile – such as an alcohol, amine, or enolate – displaces the leaving group of an acyl derivative – such as an acid halide, anhydride, or ester.The resulting product is a carbonyl-containing compound … WebTrimethylsilyldiazomethane is the organosilicon compound with the formula (CH 3) 3 SiCHN 2.
