## Abstract magnified image A serious of imidacloprid analogues have been synthesized from novel chloronicotinaldehydes. The chloronicotinaldehydes are the important synthons obtained from Vilsmeier reaction of various enamides. Thus synthesized imidacloprid analogues are new heterocyclic compounds
Imidacloprid analogues containing a nitroalkylidene instead of a nitroguanidine unit have been prepared and evaluated for investigation as potential insecticides. No nitroalkylidene analogue showed signiรcant activity against the test insects.
## Abstract Hydrotalciteโlike compounds (HTlc) were first modified by sodium dodecyl sulfate (SDS), then the intercalation of imidacloprid (IM) into modified HTlc was carried out in mixed solvent of toluene/ethanol by an evaporating solvent enhanced intercalation method, obtaining IMโSDSโHTlc nanoh
## Abstract A fiveโstep synthesis of the neonicotinoid insecticide imidacloprid (**1**) labelled with ^15^N is reported in an overall yield of 10%. The stable isotope ^15^N was introduced in the pyridine part by reaction of ^15^NH~3~ with coumalic acid methyl ester (**2**) to ^15^__N__โhydroxy nico
