method. N-Benzyl-Nmethylaminomethyllithium (I) was found to readily undergo a 1,2-anionic rearrangement to give N-lithio-N-methyl-β-phenethylarnine, a reaction analogous to the “Wittigrearrangement” of metalated ethers. A synthetically useful nucleophilic methylaminomethylation of an aldehyde [i.e., RCHO to RCH(OH)CH2NHCH3] has been effected through the use of (I).

α‐silylamine hydrochloride salts in 92–98% yields. The influence of structure of α‐silylamines and solvent on the degree of conversion was displayed. The interaction of α‐silylamines with CCl4 was studied by NMR, ESR, and IR spectroscopy. C‐centered radicals of α‐silylamines were detected by ESR spectroscopy with spin traps (MNP, ND, and PBN) in reaction mixtures in CH3CN and C6H6 and it show the radical character
