CH2=CRCOO(CH)(2)NMe3Cl (R = H or Me) were converted to resp. salicylates, D,L-lactates, saccharinates, nitrates(V) or acesulfam salts (ionic liqs.), identified and studied for their deterrent activity on adults of wheat weevil (Sitophilus granarius) and confused flour beetle (Tribolium confusum) as well as on larvae of Khapra beetle (Trogoderma granarium) and confused flour beetle (Tribolium confusum). Most of the prepd. ionic liqs. showed a biolog. activity but lower than that of azadirachtidine used for comparison.
