Cyclohexane derivs. I[R, R1, R2 = cyclohexyl, Pr, allyl; cyclohexyl, Pr, Et; cyclohexyl, Et, allyl; cyclohexyl, Et, Et; cyclopropyl, Pr, allyl; cyclopropyl, Pr, Et; cyclopropyl, Et, allyl; cyclohexyl, Me, allyl were prepd. by reaction of II with NH2OR2. Herbicidal data of I against Digitaria adscendens, Avena fatua, Chenopodium album, and Echinochloa crusgalli were given. Thus, 1.3g NH2OCH2CH:CH2 was added to 3g II (R = cyclohexyl, R1 = Pr) in EtOH and the mixt. stirred 5 hr at room temp. to give 2.5 g I (R = cyclohexyl, R1 = Pr, R2 = allyl).
