Antipyrine derivatives I (Z = O, S; Z1 = CH2, CH2OCH2; n = 0, 1, 2, 3) were prepared as open-chain crown ether analogs. Thus, refluxing diethylene glycol ditosylate with 4-hydroxyantipyrine and K2CO3 in acetone for 15 h gave I (Z = O, Z1 = CH2OCH2). The activities of I as phase-transfer catalyst for iodination of 1-bromoctane with NaI, or KI were reported.
