Silicon Containing Carbamates with Insecticidal Activity

5 Silicon Containing Carbamates with Insecticidal Activity 

Compound 103b was found to be more active than the isomeric silicon derivatives 104b and 105b. This structure-activity relationship is comparable to that of the corresponding carbon analogues 104a resp. 105a. 

Comparative investigations of insecticidal properties of the analogous compounds 103a and 103b against Culex pipiens quinquefasciatus and Musca domestica also led to similar results.
