WebCyclopropane reacts readily with bromine to form 1,3-dibromopropane1 and reacts with sulfuric acid to give 1-propylsulfuric acid2. Cyclobutane does not react with either of these reagents, but some cyclobutanes undergo C−C bond cleavage with transition metal species3. It is very difficult to cleave the C−C bonds of cyclopentane and WebOne common method of cyclopropane synthesis is the reaction of carbenes with the double bond in alkenes or cycloalkenes. Methylene, H 2 C, ... If bromine is added to cyclopentene, we might anticipate two products which differ in how the bromine atoms are geometrically related to each other.
