In the case of the 7<font face="Symbol">a</font>-hydroperoxy-CA degradation, the isomer 7<font face="Symbol">a</font>-hydroxy-CA is present in a high proportion, while the 7<font face="Symbol">b</font>-isomer is generated in a larger amount from the 7<font face="Symbol">b</font>-hydroperoxy-CA. The thermal degradation of the trimethylsilyl derivatives (TMS) of the 7-hydroperoxy-CA gives rise to many products, of which several components are the same as those obtained from the corresponding non silylated 7-hydroperoxy-CA isomer. We have found an unexpectedly high amount of the TMS derivative of the 7-hydroperoxy-CA (7<font face="Symbol">a</font>- or 7<font face="Symbol">b</font>-isomers). Traces of free 7<font face="Symbol">a</font>-hydroperoxy-CA, from thermal degradation of each 7-hydroperoxide-CA TMS (7<font face="Symbol">a</font>- and 7<font face="Symbol">b</font>-isomers), were also found.}, number={3}, journal={Grasas y Aceites}, author={Botolomeazzi, R. and Pizzale, L. and Lercker, G.}, year={2000}, month={Jun.}, pages={163–167} }
