This invention describes 2,4-diamino-5-iodopyrimidines II where R, R1, R2, and R3 are independently selected from hydrogen, alkyl, cycloalkyl, alkoxyalkyl, alkoxyalkoxyalkyl, and arylalkyl; or, R1 and R2, and R3 and R, each independently, when taken together with pentylene or 3-oxapentylene, form piperidine and morpholine ring systems respectively; and R4 is hydrogen or lower alkyl. These compounds are useful intermediates in the preparation of insecticides I where U is an optionally substituted alkenylene. <IMAGE> I <IMAGE> II
