WebTreatment of a cyclic ketone with diazomethane is a method for accomplishing a ring-expansion reaction. For example, treatment of cyclohexanone with diazomethane yields cycloheptanone. Propose a mechanism. The Favorskii reaction involves treatment of an -bromo ketone with base to yield a ring-contracted product. WebAldehydes (RCHO) and ketones (RCOR') are reactive varieties of the more general functional group called carbonyls, which have a carbon-oxygen double-bond (C=O). The …
