Addition of non-stabilized organolithium reagents to O-alkyl aldoximes in the presence of boron trifluoride etherate gives rise to O-alkyl hydroxylamines. The Z oxime isomer preferentially reacts under these reaction conditions.
decomposition of the methanesulfonyl radical into the methyl radical and the subsequent transfer of an iodine atom or phenyl telluride group was used to develop a tin-freeradical acylation reaction (see scheme; V-40=1,1'-azobis(cyclohexane-1-carbonitrile). The key was finding reactionconditionsunder which the I or PhTe transfer is faster than the direct addition of the alkyl radical to the methanesulfonyl oxime
