The dihydroxycarbonyl products of the isomerizationreactions of the s/gifchars/beta2.gif" BORDER=0 ALIGN="middle">-hydroxyalkoxy radicals formedafter OH radical addition to the 1-alkenes 1-butenethrough 1-octene have been observed by direct airsampling atmospheric pressure ionization mass spectrometry (API-MS). The experimental data obtainedprovide direct evidence for s/gifchars/beta2.gif" BORDER=0 ALIGN="middle">-hydroxyalkoxy radicalisomerization via a six-member transition state. Ourdata show that the importance of s/gifchars/beta2.gif" BORDER=0 ALIGN="middle">-hydroxyalkoxyradical isomerization in the OH radical-initiatedreactionsof the 1-alkenes increases with carbon number,being unimportant for 1-butene and dominating for1-heptene and 1-octene.
