The invention relates to a method of controlling insects (in particular insects of the order Hemiptera, especially aphids and whitefly) that are resistant to neonicotinoid insecticides, to methods of controlling insects whereby undesired insects are affected but beneficial arthropods are not affected, using compounds of formula I(where A and R1 are as defined above) and, further, to novel compounds of formula I which are useful in the aforementioned methods and/or which possess enhanced insecticidal properties, and to compositions containing said compounds.
A compound of formula I, (I), wherein A, Q, R
1
, and R
2
, are as defined in claim
1
. Furthermore, the present invention relates to intermediates used to prepare compounds of formula (I), to methods of using them to combat and control insect, acarine, nematode and mollusc pests and to insecticidal, acaricidal, nematicidal and molluscicidal compositions comprising them.

cross-couple unactivated secondary alkyl iodides with various N-, O-, and C-based nucleophiles. This strategy harnesses the ability of photoredox-generated phenyl radicals to mediate halogen-atom transfer (XAT) and convert alkyl iodides into the corresponding radicals. These species engage in a second catalytic cycle, mediated by copper, which enables C–N/O/C bond formation with the various nucleophiles
在这里,我们报告了一种工具箱策略,用于将未活化的仲烷基碘与各种基于 N、O 和 C 的亲核试剂交叉偶联。该策略利用光氧化还原产生的苯基自由基介导卤素原子转移 (XAT) 并将烷基碘转化为相应自由基的能力。这些物质参与由铜介导的第二个催化循环,从而能够与各种亲核试剂形成 C-N/O/C 键。
