Dithianes substituted at the 2 and 5 positions, and their sulfoxides, are insecticidal agents. Optimum activity was observed for 5-/-butyl derivatives with either 2-phenyl or 2-cyano substituents <92Mi 608-02). The mode of action is thought to be similar to that of the insecticidal 2,6,7-trioxabicyclo[2.2.2]octanes. Investigations of the oxidation, metabolism, and photoactivity of these materials have been carried out <92Mi 608-03,92Mi 608-04,94JMC133). In related work, 2,5-disubstituted-... 

Co-ozonolysis of /< r/-butylethene (3,3-dimethyl-l-butene) in the presence of benzoyl cyanide gave as major product (55%) 3-cyano-3-phenyl-l,2,4-trioxolane 103 along with 13% of the ft /t-butyl-substituted 1,2,4-trioxolanes 108 as a mixture of stereoisomers in 53 47 Z/E ratio which could be assigned from nuclear Overhauser effect (NOE) data, as only the (Z) compound shows an NOE enhancement (across the 1,2,4-trioxolane ring) of the ortho-phenyl protons upon irradiation of the Bu methyl groups (Equation (10) and Figure 5).
