Abstract: The reaction of N-tert-alkyl-substituted propargylic amines with trialkylalanes in the presence of 20 mol.% Cp2ZrCl2 was studied. The pattern of the products depended on the nature of substituents at the nitrogen atom. N-tert-Alkyl-N-arylmethyl-substituted propargylic amines… read more here.

Abstract: We report the sequence-regulated radical additions of tert-alkyl radicals to two different olefins controlled by a Cu catalyst, which we term the "atom-transfer radical addition-substitution" reaction. The reactions of α-bromocarbonyl compounds, such as tert-alkyl radical… read more here.
