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.
A mass spectrometric study of dimethyl ester trimethylsilyl ether derivatives of some 3-hydroxydicarboxylic acids
摘要:
AbstractThe fragmentation pathways for the dimethyl ester trimethylsilyl ether derivatives of some 3‐hydroxydicarboxylic acids have been found by using B/E 2nd B2/E linked scans and isotope substitution techniques. Most of the fragments are due to ionization at silicon, which induces a fragmentation pattern that intimately reflects the structure of the compounds.
