alpha-amino-alpha-carbonylmethyl radicals 8 have been recorded. No coalescence temperature for the rotation of the two NMe groups was found at temperatures below the decomposition temperature of the radicals. From known coalescence temperatures and rotationalbarriers of substituted methyl radicals the rotationalbarrier of >/=17 kcal mol(-)(1) was estimated for the (*)C-N bond in the radicals 8.
