A mass spectrometric study of the dimethyl ester trimethylsilyl enol ether derivatives of some 3-oxodicarboxylic acids
摘要:
AbstractThe fragmentation pathways for the dimethyl ester trimethylsilyl enol ether derivatives of some 3‐oxodicarboxylic acids have been found by using B/E and B2/E linked scans, collisional activated decomposition and isotope substitution techniques. The trimethylsilyloxy group strongly directs the decomposition processes, and induces a fragmentation pattern that intimately reflects the structure of the compounds.
