The mass spectra of twelve trisubstituted oyolopropanes have been analyzed and the results may bo summarized as follows:(1) For the cylopropanes with benzoyl,carbonyl or oarbomethogyl substituents,a-cleavage predominated leading to the formation of the [M-C6H5CO]+,[M-COOH]+ and [M-COOCH3]+ ion peaks,so their moleoular ion peak were very small.(2) For traps-1,2-oyolopropane dioarboaylio a,oid the notable peaks were [M-H20]+ and [M-H2O-CO]+,but for the ois isomer it was [M-H2O]+.
