Me(2)CH(C=NOH)C(5)H(11)-t (7H), among others, did not lead to isolable iminoxyls. A new, convenientsynthesis 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.
