Me(2)CH(C=NOH)C(5)H(11)-t (7H), among others, did not lead to isolable iminoxyls. A new, convenient synthesis of symmetrical tertiary imines from tert-RCl, tert-RCN, and Na is described. Radical t-Bu(2)C=NO(*) (8) and cyclohexene readily gave the allylic substitution product, 2,2,4,4-tetramethyl-3-hexanone O-(2'-cyclohexen-1'-yl)oxime.
为了寻找持久性提高的自由基,合成了一系列通式为R(C = NO(*))R(1)的亚
氨基自由基,其中R和R(1)通常为叔级。三个新的自由基被分离为蓝色液体:Et(3)C(C = NO(*))Bu-t(1),tC(5)H(11)(C = NO(*))Bu-t(2 )和(tC(5)H(11))(2)C = NO(*)(3)。
肟的氧化Et(3)C(C = NOH)Ph(4H),PhCH(2)CMe(2)(C = NOH)Bu-t(5H),PhCMe(2)(C = NOH)Bu-t (6H)和Me(2)CH(C = NOH)C(5)H(11)-t(7H)等未产生可分离的亚
氨基氧基。描述了一种从叔-RCl,叔-RCN和Na合成对称叔叔胺的新方法。自由基t-Bu(2)C = NO(*)(8)和
环己烯容易得到烯丙基取代产物2,2,4,4-四甲基-
